https://en.wikipedia.org/wiki/William%20Spence%20%28mathematician%29
William Spence (born 31 July 1777 in Greenock, Scotland – died 22 May 1815 in Glasgow, Scotland) was a Scottish mathematician who published works on the fields of logarithmic functions, algebraic equations and their relation to integral and differential calculus respectively. Early life, family, and personal life Spence was the second son to Ninian Spence and his wife Sarah Townsend. Ninian Spence ran a coppersmith business, and the Spence family were a prominent family in Greenock at the time. From an early age, Spence was characterised as having a docile and reasonable nature, with him being mature for his age. At school he formed a life-long friendship with John Galt, who documented much of his life and his works posthumously. Despite having received a formal education until he was a teenager, Spence never attended university, instead he moved to Glasgow where he lodged with a friend of his fathers, learning the skills of a manufacturer. Two years after his father's death in 1795, Spence returned to Greenock in 1797. With the support of Galt and others, he established a small literary society, wherein once a month they read a range of essays on varying subjects, this society met frequently until 1804. After this, Spence visited many places in England, he lived in London for a few months where, in 1809, he published his first work. In 1814, he published his second work, getting married in the same year – Spence intended to live in London, and began his journey back before becoming ill, having travelled as far as Glasgow, he died in his sleep due to illness. Spence held an interest in musical composition, and played the flute. Published works Spence published An Essay on the Theory of the Various Orders of Logarithmic Transcendents: With an Inquiry Into Their Applications to the Integral Calculus and the Summation of Series in 1809. Throughout his work, he displayed a familiarity with the work of Lagrange and Arbogast, which is notable since at the time very few were familiar with their works. In his preface he derived the binomial theorem and mainly focused on the properties and analytic applications of the series: which he denoted with . He went on further to derive nine general properties of this function in a table. Spence also wrote on presenting analytical mathematics without the need of demonstrating the practical applications of such work. Spence continues to write that the functions can be expressed as iterations of the previous n term: , , . . . , for all values of x. Spence goes on to calculate the values of: to nine decimal places, in a table, for all integer values of from 1 to 100, the first ever of its kind. These functions became known as the polylogarithm functions, with this particular case often called Spence's function after Spence. Later on he also created a similar table for . Spence published his last work, Outlines of a theory of Algebraical Equations, deduced from the principles of Harriott, and exten

https://en.wikipedia.org/wiki/Convex%20cap
A convex cap, also known as a convex floating body or just floating body, is a well defined structure in mathematics commonly used in convex analysis for approximating convex shapes. In general it can be thought of as the intersection of a convex Polytope with a half-space. Definition A cap, can be defined as the intersection of a half-space with a convex set . Note that the cap can be defined in any dimensional space. Given a , can be defined as the cap containing corresponding to a half-space parallel to with width times greater than that of the original. The definition of a cap can also be extended to define a cap of a point where the cap can be defined as the intersection of a convex set with a half-space containing . The minimal cap of a point is a cap of with . Floating Bodies and Caps We can define the floating body of a convex shape using the following process. Note the floating body is also convex. In the case of a 2-dimensional convex compact shape , given some where is small. The floating body of this 2-dimensional shape is given by removing all the 2 dimensional caps of area from the original body. The resulting shape will be our convex floating body . We generalize this definition to n dimensions by starting with an n dimensional convex shape and removing caps in the corresponding dimension. Relation to affine surface area As , the floating body more closely approximates . This information can tell us about the affine surface area of which measures how the boundary behaves in this situation. If we take the convex floating body of a shape, we notice that the distance from the boundary of the floating body to the boundary of the convex shape is related to the convex shape's curvature. Specifically, convex shapes with higher curvature have a higher distance between the two boundaries. Taking a look at the difference in the areas of the original body and the floating body as . Using the relation between curvature and distance, we can deduce that is also dependent on the curvature. Thus, . In this formula, is the curvature of at and is the length of the curve. We can generalize distance, area and volume for n dimensions using the Hausdorff measure. This definition, then works for all . As well, the power of is related to the inverse of where is the number of dimensions. So, the affine surface area for an n-dimensional convex shape is where is the -dimensional Hausdorff measure. Wet part of a convex body The wet part of a convex body can be defined as where is any real number describing the maximum volume of the wet part and . We can see that using a non-degenerate linear transformation (one whose matrix is invertible) preserves any properties of . So, we can say that is equivariant under these types of transformations. Using this notation, . Note that is also equivariant under non-degenerate linear transformations. Caps for approximation Assume and choose randomly, independently and ac

Patrick Brendan Kennedy (20 July 1929 in Clarecastle, County Clare, Ireland - 8 June 1966 in Nottingham, England) was an Irish chess champion, and an academic in Mathematics, notable for his work in complex analysis. Early life, family, and personal life Kennedy was the third child of Pat Kennedy and Kit O'Sullivan, his father, a master carpenter by trade, decided instead to join the police force in 1923, many on his mother's side were blacksmiths near Castlemaine. His parents moved to Ballylongford in 1936, and secured a transfer for Kennedy to attend the North Monastery secondary school in Cork. Whilst at the North Monastery School, Kennedy won the Honan Scholarship to University College Cork, where in 1949 was awarded his Bachelor's degree in Mathematics and Mathematical Physics. In the same year, Kennedy also took part in the Irish Chess Championship, and won 7 games out of 7, becoming the Irish chess Champion, he has been the only Irish Chess champion to win in such a way. After this, Kennedy was described as having a falling off in the quality of his play, and lost his title at the 1950 Championship. In 1951, Kennedy completed his Master's degree, and was recommended by his examiner V. C. A. Ferraro, who at the time was a professor of applied mathematics at the University College of the South West at Exeter, to study for a Ph.D. with Walter Hayman at Exeter. Kennedy's first paper was published in 1953, titled On a conjecture of Heins, which concerned a conjecture of Heins on subharmonic functions and gives positive results. That same year he was appointed as an assistant lecturer in mathematics at the University of Aberystwyth, and by 1954 he was awarded a Ph.D. by the National University of Ireland for his thesis Asymptotic Values on Integral Functions. He married Pamela Fishwick in March 1954, and had three children, David Patrick Kennedy, Anne Deirdre Kennedy, and Jane C Deborah Kennedy. Since Kennedy lived in Wales at the time, he had wanted to avoid national service for the English, and so took a lecturer position at University College Cork in 1954, his objectives were to modernise courses and raise standards, and his research output increased. Hayman characterises Kennedy's attitude to academic politics as "black and white", and Kennedy wasn't afraid to work hard both in his research and on committee to achieve productive outcomes. In 1956, he was appointed professor of mathematics at Cork, and awarded the D.Sc. by the National University of Ireland in 1960, he was elected a Fellow of the Royal Irish Academy in 1962. He was appointed the first professor of mathematics at the University of York in 1962, which planned to open the next year. He worked at building the mathematics library and appointed staff to the mathematics department. Kennedy took his life in 1966 on the night of 8 June, the coroner explained it was a combination of a psychiatric illness and added pressure of work, with his wife, Fishwick stating: "[He] set h

William James Macdonald FRSE was born on 14 December 1851 in Scotland. He is known for being a pioneer of the introduction of modern geometry to the mathematical curriculum in schools and for being one of the founding members of the Edinburgh Mathematical Society. Biography Macdonald was born in Huntly, Aberdeenshire, but moved to the coastal town of St Andrews when he was young. There he got an education in Madras College, and became dux of the college in 1868. After completing his school education he entered the University of St Andrews, where he studied a variety of subjects including mathematics, English literature, Latin, Greek, chemistry, and philosophy. While there Macdonald won many prizes, including the Miller prize given to the student who did the best work in 1870, 1871, and 1872, the Gray prize in 1872 for an essay on spectrum analysis, and the Arnott prize, also in 1872. After graduating, Macdonald was appointed assistant to the Mathematics Department in Madras College, but only taught there for a short time before accepting a role as Mathematics Master at Merchiston Castle school in Edinburgh. He soon after accepted a role at Daniel Stewart’s College where he spent the rest of his career. Between 1898 and 1899, he was the president of the Scottish Secondary Teachers' Association. He died in Edinburgh on 29 December 1941. Accomplishments Macdonald was a pioneer in the introduction of modern geometry to the mathematical curriculum. He wrote Higher Geometry: Containing an Introduction to Modern Geometry and Elementary Geometrical Conics, a text which was widely used in schools and colleges to teach geometry. He was a founding member of the Edinburgh Mathematical Society, and was honoured by the society when he was elected as president for 1887-88 session. On the 1st of February 1886 he accepted a fellowship to the Royal Society of Edinburgh after being proposed by William Swan, John Sturgeon Mackay, George Chrystal, and Sir Thomas Muir. In June 1914, he was offered the degree of LL.D by the Senatus Academicus of the University of St Andrews, but he respectfully declined the honour.

https://en.wikipedia.org/wiki/Quasiconvexity%20%28calculus%20of%20variations%29
In the calculus of variations, a subfield of mathematics, quasiconvexity is a generalisation of the notion of convexity. It is used to characterise the integrand of a functional and related to the existence of minimisers. Under some natural conditions, quasiconvexity of the integrand is a necessary and sufficient condition for a functional to be lower semi-continuous in the weak topology, for a sufficient regular domain . By compactness arguments (Banach–Alaoglu theorem) the existence of minimisers of weakly lower semicontinuous functionals may then follow from the direct method. This concept was introduced by Morrey in 1952. This generalisation should not be confused with the same concept of a quasiconvex function which has the same name. Definition A locally bounded Borel-measurable function is called quasiconvex if for all and all , where is the unit ball and is the Sobolev space of essentially bounded functions with essentially bounded derivative and vanishing trace. Properties of quasiconvex functions The domain can be replaced by any other bounded Lipschitz domain. Quasiconvex functions are locally Lipschitz-continuous. In the definition the space can be replaced by periodic Sobolev functions. Relations to other notions of convexity Quasiconvexity is a generalisation of convexity for functions defined on matrices, to see this let and with . The Riesz-Markov-Kakutani representation theorem states that the dual space of can be identified with the space of signed, finite Radon measures on it. We define a Radon measure by for . It can be verfied that is a probability measure and its barycenter is given If is a convex function, then Jensens' Inequality gives This holds in particular if is the derivative of by the generalised Stokes' Theorem. The determinant is an example of a quasiconvex function, which is not convex. To see that the determinant is not convex, consider It then holds but for we have . This shows that the determinant is not a quasiconvex function like in Game Theory and thus a distinct notion of convexity. In the vectorial case of the Calculus of Variations there are other notions of convexity. For a function it holds that These notions are all equivalent if or . Already in 1952, Morrey conjectured that rank-1-convexity does not imply quasiconvexity. This was a major unsolved problem in the Calculus of Variations, until Šverák gave an counterexample in 1993 for the case and . The case or is still an open problem, known as Morrey's conjecture. Relation to weak lower semi-continuity Under certain growth condition of the integrand, the sequential weakly lower semi-continuity (swlsc) of an integral functional in an appropriate Sobolev space is equivalent to the quasiconvexity of the integrand. Acerbi and Fusco proved the following theorem: Theorem: If is Carathéodory function and it holds . Then the functional is swlsc in the Sobolev Space with if and only if is quasiconvex. Here is a p

In January 1951, he was appointed as lecturer of mathematics at the university and taught at several different colleges until August 1957. In September 1957, Puri moved the United States as he got appointed as an instructor and graduate student at the University of Colorado, Boulder. In 1958 he moved to the University of California, Berkeley, where he became a research assistant in statistics. His studies were supervised by Erich Lehmann and he was awarded his doctorate in 1962 after submitting a thesis titled Asymptotic Efficiency of a Class of c-Sample Tests. After this, he was appointed as an assistant professor and later associate professor at the Courant Institute of Mathematical Sciences in New York. He gained full professorship at Indiana University, Bloomington. Accomplishments On February 20, 2003, Puri was honoured with the title of College of Arts and Sciences Distinguished Research Scholar.

https://en.wikipedia.org/wiki/Forza%20Football
Forza Football is a Sweden-based football media company. The app Forza Football features live-scores, statistics and video highlights for both men's and women's football all over the world. The company also focusses on "making the world of football a better place", which includes running a football academy for children in Cambodia and collaborating with organisations like Transparency International, Stonewall or Kick It Out. History The company was founded in 2012 in Gothenburg, Sweden, by Patrik Arnesson, Erik Heinemark and Anders Elfving under the name Football Addicts. Within the first month after the release, their app Live Score Addicts was downloaded by over 300,000 users. In April 2014, the company announced the decision to change the name of the live-score app to Forza Football, which came with a variety of new features as well as a whole new design and user interface. The company took the pledge in the #WhatIf campaign organised by Women In Football in May 2018, with the goal to offer the same coverage of women’s football as for the men’s game. Later that year, together with Kazakoff Design, Forza Football was awarded the top distinction for communication design, the Red Dot: Grand Prix, in the Red Dot Design Award 2018. In 2021, they had a revenue of around SEK 56 million and a profit of SEK 9.8 million. Since April 2022, Jonas Linné is the CEO of the football app, while founder Patrik Arnesson will focus more on the NFT business through the company Forza Ikonia. Forza Football collaborated with investigative journalism platform Blankspot and creative agency Forsman & Bodenfors to release Cards of Qatar in June 2022. Instead of the World Cups' star players, the Cards of Qatar profile workers that have been injured or killed on the job during preparations for the 2022 FIFA World Cup. Later that year, the reportage series won the Stora Journalistpriset 2022 in the category "Innovator of the Year". In October 2022, Forza Football was listed as one of Sweden's 90 hottest fast-growing tech companies by new business news site Breakit. Surveys Homophobia in football In October 2014, 30,000 football fans participated in a survey regarding attitudes towards homosexuality in football. Louise Taylor of The Guardian analysed the findings of the poll: "Although the results are varied and reflect the cultural contexts of the regions in which respondents live the overall message is that homophobia among football supporters seems to be a diminishing, albeit slowly, problem." A similar survey of 50,000 fans took place in December 2017. The results showed that 76% of the participants would feel comfortable if a player in their national team came out as gay or bisexual. In an online article for Forbes, Steve Price titled that the poll makes a "grim reading for U.S. Soccer" on LGBT tolerance. Racism in football In 2018, Forza Football worked together with Kick It Out on a survey to identify global attitudes and issues in regards to racial equa

Batters generally aim for a higher exit velocity in order to give opposing fielders less time to react and attempt a defensive play; however, many batters are still able to accrue hits without a high exit velocity. A pitcher will attempt to limit the exit velocity on the opposing batter's contact in order to allow the fielders or themself a better chance at making an out. Exit velocity was first tracked by Major League Baseball (MLB) in 2015 with the introduction of Statcast. In MLB and many other North American baseball leagues, exit velocity is measured and presented in miles per hour. Origins For most of baseball's history, there were no commonplace methods to quantify how hard-hit a batted ball was — the only aspect of the ball's speed being tracked was how fast the pitcher threw it, measured using various evolutions of radar guns. In 2015, MLB introduced Statcast technology to all 30 of its ballparks, in part to track exit velocity. The league released its initial data the following year in a summary of the 2015 season's statistical notabilities. Throughout the 2016 season, more aspects of exit velocity were gradually rolled out to fans. MLB launched Baseball Savant in 2016 to provide fans easy access to exit velocity and other Statcast-recorded data. External factors Ballparks Since every MLB stadium has its own unique set of dimensions and intricacies, there has been an observed ballpark-to-ballpark difference in exit velocity stats despite attempts to curtail it. MLB originally installed TrackMan radar technology but switched to the optical-based Hawk-Eye system in 2020 — with both systems, the league was unable to avoid variances in data collection based on each ballpark. When Statcast is unable to accurately record exit velocity data for a batted ball, either because of ballpark factors or some other reason, it imputes a value in its place. Equipment Exit velocity can vary based on whether or not the ball is moisturized with a humidor. From April 7 to May 22, 2021, the average exit velocity was with a humidor and without a humidor. During the same span of days in 2022, the average with a humidor was and without a humidor. Uses Since its introduction, MLB teams have used the exit velocity stat to gauge a batter's abilities. Transversely, exit velocity can be analyzed to improve a pitcher's results, especially those prone to giving up hard contact. Statcast technology in MLB ballparks allows teams to analyze exit velocity data points in real-time during games and make adjustments accordingly. The use of exit velocity stats has been criticized by some. In 2018, Chicago Cubs manager Joe Maddon expressed his thoughts on advanced stats, stating: "Keep your launch angles, keep your exit velocities, give me a good at-bat." Maddon added that exit velocity and similar stats should instead be used
https://en.wikipedia.org/wiki/Ari%20Nagel
Ari Nagel () is an American mathematics professor and a sperm donor who has fathered more than 100 children . He has been nicknamed the Sperminator or the Target Donor, after the American retail corporation in whose stores some of his artificial-insemination donations were performed. Early life Ari Nagel was born to an Orthodox Jewish family in Monsey, New York, as the fifth of seven children. He spent his childhood in Monsey, attending school at Yeshiva of Spring Valley and Yeshiva Shaarei Torah, and later studied at St. John's University in New York City. Nagel received a large monetary settlement from a motorcycle accident and traveled around the world, after which he became irreligious. He also studied at the London School of Economics. After returning to New York, he became a professor at the Kingsborough Community College of the City University of New York teaching mathematics and computer science. Nagel's first child was born in 2003 as a result of an unintended pregnancy. He married the mother but they maintained separate apartments. Sperm donation When his first son was a toddler, Nagel made his first sperm donation to a lesbian couple who advertised on Craigslist. Shortly thereafter he donated to a single woman he knew, following which he registered in the Known Donor Registry and donated a couple of times a year. In 2016, the New York Post reported that Nagel had fathered 22 children, nicknaming him the "Sperminator". Shortly after the story was published, the New York State Department of Health sent Nagel a letter informing him that operating an unlicensed sperm bank was illegal, but did not escalate the matter. As of 2021, Nagel continued to operate outside of any regulatory framework, and provides sperm donations without formal legal contracts. Nagel maintains contact with many of the children he has fathered, but does not generally support the children financially. He has been successfully sued by five mothers (of nine children) for child support, and half of his university paycheck is garnished towards these payments. Nagel often travels to prospective recipients, with the recipients paying for his flight fare, and the sperm is provided free of charge as a donation. Nagel originally made many of his donations with natural insemination, but later switched to artificial insemination, delivering his sperm in a "cup" to protect himself, and the mothers to whom he donates sperm, from the risks of frequent unprotected sex. Some of his artificial donations were performed in public restrooms, leading to the nickname "Target Donor" after it was reported that some donations were made in Target department stores. In 2017, Nagel deposited sperm with six different sperm banks in Israel. In 2018, Israeli authorities banned him from donating sperm; his appeal against the decision was rejected by the Supreme Court of Israel. The court ruled that it was "doubtful he [Nagel] can function as an actual father" due to the number of his children. I
https://en.wikipedia.org/wiki/Thom%27s%20first%20isotopy%20lemma
In mathematics, especially in differential topology, Thom's first isotopy lemma states: given a smooth map between smooth manifolds and a closed Whitney stratified subset, if is proper and is a submersion for each stratum of , then is a locally trivial fibration. The lemma was originally introduced by René Thom who considered the case when . In that case, the lemma constructs an isotopy from the fiber to ; whence the name "isotopy lemma". The local trivializations that the lemma provide preserve the strata. However, they are generally not smooth (not even ). On the other hand, it is possible that local trivializations are semialgebraic if the input data is semialgebraic. The lemma is also valid for a more general stratified space such as a stratified space in the sense of Mather but still with the Whitney conditions (or some other conditions). The lemma is also valid for the stratification that satisfies Bekka's condition (C), which is weaker than Whitney's condition (B). (The significance of this is that the consequences of the first isotopy lemma cannot imply Whitney’s condition (B).) Thom's second isotopy lemma is a family version of the first isotopy lemma. Proof The proof is based on the notion of a controlled vector field. Let be a system of tubular neighborhoods in of strata in where is the associated projection and given by the square norm on each fiber of . (The construction of such a system relies on the Whitney conditions or something weaker.) By definition, a controlled vector field is a family of vector fields (smooth of some class) on the strata such that: for each stratum A, there exists a neighborhood of in such that for any , on . Assume the system is compatible with the map (such a system exists). Then there are two key results due to Thom: Given a vector field on N, there exists a controlled vector field on S that is a lift of it: . A controlled vector field has a continuous flow (despite the fact that a controlled vector field is discontinuous). The lemma now follows in a straightforward fashion. Since the statement is local, assume and the coordinate vector fields on . Then, by the lifting result, we find controlled vector fields on such that . Let be the flows associated to them. Then define by It is a map over and is a homeomorphism since is the inverse. Since the flows preserve the strata, also preserves the strata.

https://en.wikipedia.org/wiki/Tony%20O%27Farrell
Tony O'Farrell (born Anthony G. O'Farrell in 1947 in Dublin) is an Irish mathematician who is Professor Emeritus at Maynooth University. He has been in the Mathematics and Statistics Department there since 1975. Early life He was born in Dublin and grew up there and in Tipperary. Education and career He attended University College Dublin (UCD) earning a BSc in mathematical science (1967). After a year working for the Irish Meteorological Service, he returned to UCD for his MSc (1969). He then moved to the USA, to Brown University from which he earned a PhD in 1973, for a thesis on "Capacities in Uniform Approximation" done under Brian Cole. After two years at the University of California, Los Angeles (UCLA), during which he published extensively, in 1975 he returned to Ireland as Professor of Mathematics at St. Patrick's College, Maynooth (later Maynooth University), outside Dublin. This appointment was notable for two reasons: he was only 28, and, while Maynooth had lay lecturers and senior lecturers, he was the first layman appointed to a chair at this traditionally pontifical institution. O'Farrell has long been active in the Irish Mathematical Society, serving as president in 1983 and 1984, and as editor of the Bulletin of the IMS since 2011. In 1981 he was elected to the Royal Irish Academy. From 1992-1995, he also served as head of the Computer Science Department at Maynooth. In 2002, O'Farrell established Logic Press which publishes mathematics books at various levels in both English and Irish. These range from the Irish Mathematical Olympiad Manual to undergraduate and postgraduate level texts and research monographs. In 2012, he formally retired from Maynooth, though he remains very active in many arenas. Hamilton Walk In 1990 O’Farrell established the annual Hamilton Walk, which commemorates the 16 October 1843 discovery of quaternions by William Rowan Hamilton. It starts at Dunsink Observatory in County Dublin, just west of the city, and follows the Royal Canal east to Broom Bridge. Over the decades, this has grown in popularity and stature, attracting Nobel laureates and Fields Medallists. O'Farrell's younger colleague Fiacre Ó Cairbre took over the organisation of the walk at the end of the 1990s, but O'Farrell always gives a speech at Broom Bridge. In 2018, O’Farrell and Ó Cairbre received the 2018 Maths Week Ireland Award, for "outstanding work in raising public awareness of mathematics" resulting from the founding and nurturing the Hamilton Walk.

A κ-Weibull distribution corresponds to a κ-deformed Rayleigh distribution when and a Rayleigh distribution when and . Applications The κ-Weibull distribution has been applied in several areas, such as: In economy, for analyzing personal income models, in order to accurately describing simultaneously the income distribution among the richest part and the great majority of the population. In seismology, the κ-Weibull represents the statistical distribution of magnitude of the earthquakes distributed across the Earth, generalizing the Gutenberg–Richter law, and the interval distributions of seismic data, modeling extreme-event return intervals. In epidemiology, the κ-Weibull distribution presents a universal feature for epidemiological analysis.

https://en.wikipedia.org/wiki/List%20of%20carillons%20in%20Belgium
Carillons, musical instruments of bells in the percussion family, are found throughout Belgium. Several institutions maintain registries on the location and statistics of carillons. Some registries specialize in counting specific types of carillons. For example, the War Memorial and Peace Carillons registry counts instruments which serve as war memorials or were built in the name of promoting world peace (and tracks five in Belgium); the counts carillons throughout the country, along with the rest of the world. Two Belgian carillon associationsthe Flemish Carillon Association and the Walloon Carillon Associationcount carillons in their respective regions. According to their registries, there are 94 carillons in Belgium: 70 in the Flemish Region, 22 in the Walloon Region, and 2 in the Brussels Capital Region. They are distributed across 77 different cities; several are located within the same city, and two are even within the same buildingat St. Rumbold's Cathedral in Mechelen. The population has a wide range in total weights, with bourdons spanning between . They also span a wide range of notes, from 21 (which the Flemish association considers a carillon despite failing its definition that requires at least 23) up to 64. Many carillons were constructed over several centuries by several bellfounders; a minority are constructed entirely by a single bellfounder. The majority of carillons are transposing instruments, and often transpose such that the lowest note on the keyboard is B or C. According to the , the carillons in Belgium account for 14 percent of the world's total and is consequently considered one of the "great carillon countries" along with the Netherlands and the United States. Brussels Despite not being a part of their respective regions, both the Flemish Carillon Association and the Walloon Carillon Association track the number of carillons located in the Brussels Capital Region, of which there are two. The larger both in terms of weight and number of bells is located at the Cathedral of St. Michael and St. Gudula. The smaller is located at the Palace of the Nation, Belgium's federal parliament building. Constructed in the 20th century, these carillons are much newer relative to others in the country. Brussels once had nine carillons in 1541; none survived past 1914. Flanders The Flemish Carillon Association maintains a registry of carillons in the Flemish Region. According to the organization, there are 70 carillons located in Flanders. They are distributed across 56 different cities; several are located within the same city, and two are even within the same buildingat St. Rumbold's Cathedral in Mechelen. The carillons have a wide range in total weights, with bourdons spanning between .

https://en.wikipedia.org/wiki/Wang%20Qiming
Wang Qiming (; June 4, 1941 – April 7, 1989) was a Chinese mathematician who was known for his work in differential geometry. He was considered as one of the best differential geometers in China of the time. Biography Wang Qiming was born in Yan'an, Shaanxi. In 1960, he graduated from Beijing 101 Middle School and was admitted to the five-year bachelor's degree programme of the Department of Mathematics of the University of Science and Technology of China. In 1965, he entered the Institute of Mathematics of the Chinese Academy of Sciences to study under Wu Wenjun. Once Wang pointed out a mistake that Wu made in a lesson and told Wu the German book upon which he based. Wu was greatly impressed. After the institute had recovered in early 1970s from the disruption of the Cultural Revolution, Wang worked intensely in differential geometry and topology. After mainland China had reopened to the world, Wang actively engaged in international research cooperations. He was one of the first Chinese visiting scholars to the United States in 1978 when he visited the University of California at Berkeley for two years. Later, he also visited the IHES, Max-Planck-Institut, the CIME in Italy and University of Texas at Austin. Academic career Wang was a senior researcher of the Institute of Mathematics of the Chinese Academy of Sciences, a member of its academic committee and the person in charge of graduate student affairs. Wang had also been the acting deputy director of the institute. Since 1988, Wang had been the deputy editor-in-chief of the Chinese mathematics journal 数学进展 (Advances in Mathematics (China)). He was a committee member of the International Centre for Theoretical Physics in Italy. Death On April 7, 1989, Wang was killed in a car accident. He was a passenger in a car whose driver was Shing-Tung Yau, and the accident occurred when Yau was making a turn. Wang had just arrived in the United States the day before and planned to visit Harvard University for several months. He would likely have become the director of the Institute of Mathematics had he returned to China after this visit. His teacher Wu Wenjun thought that Wang would certainly have been a leader of Chinese mathematics if the accident had not had happened. A memorial service was held in Beijing on July 20 that year. Research Wang Qiming worked on differential geometry and symmetric spaces. He made a number of important contributions to isoparametric functions and minimal hypersurfaces.

https://en.wikipedia.org/wiki/Kaniadakis%20Gaussian%20distribution
The Kaniadakis Gaussian distribution (also known as κ-Gaussian distribution) is a probability distribution which arises as a generalization of the Gaussian distribution from the maximization of the Kaniadakis entropy under appropriated constraints. It is one example of a Kaniadakis κ-distribution. The κ-Gaussian distribution has been applied successfully for describing several complex systems in economy, geophysics, astrophysics, among many others. The κ-Gaussian distribution is a particular case of the κ-Generalized Gamma distribution. Definitions Probability density function The general form of the centered Kaniadakis κ-Gaussian probability density function is: where is the entropic index associated with the Kaniadakis entropy, is the scale parameter, and is the normalization constant. The standard Normal distribution is recovered in the limit Cumulative distribution function The cumulative distribution function of κ-Gaussian distribution is given bywhereis the Kaniadakis κ-Error function, which is a generalization of the ordinary Error function as . Properties Moments, mean and variance The centered κ-Gaussian distribution has a moment of odd order equal to zero, including the mean. The variance is finite for and is given by: Kurtosis The kurtosis of the centered κ-Gaussian distribution may be computed thought: which can be written asThus, the kurtosis of the centered κ-Gaussian distribution is given by:or κ-Error function The Kaniadakis κ-Error function (or κ-Error function) is a one-parameter generalization of the ordinary error function defined as: Although the error function cannot be expressed in terms of elementary functions, numerical approximations are commonly employed. For a random variable distributed according to a κ-Gaussian distribution with mean 0 and standard deviation , κ-Error function means the probability that X falls in the interval . Applications The κ-Gaussian distribution has been applied in several areas, such as: In economy, the κ-Gaussian distribution has been applied in the analysis of financial models, accurately representing the dynamics of the processes of extreme changes in stock prices. In inverse problems, Error laws in extreme statistics are robustly represented by κ-Gaussian distributions. In astrophysics, stellar-residual-radial-velocity data have a Gaussian-type statistical distribution, in which the K index presents a strong relationship with the stellar-cluster ages. In nuclear physics, the study of Doppler broadening function in nuclear reactors is well described by a κ-Gaussian distribution for analyzing the neutron-nuclei interaction. In cosmology, for interpreting the dynamical evolution of the Friedmann–Robertson–Walker Universe. In plasmas physics, for analyzing the electron distribution in electron-acoustic double-layers and the dispersion of Langmuir waves.

The demographics of Brussels are monitored by Statistics Belgium. Brussels population is currently 1,222,657 as of 2022. Population The current population of Brussels (officially the Brussels Capital Region) in 2022 was 1,222,637 In recent years, the city has received a markable increase in its population. In general, the population of Brussels is younger than the national average, and the gap between rich and poor is wider. Growth rate The population growth rate within Brussels for 2021 was 0.22%. Density The density of Brussels is also high, Brussels is one of the most urbanised areas of Europe. Life expectancy The life expectancy is Brussels is 79.61 years of age in 2020. Fertility The total fertility rate within Brussels in 2019 is 1.7 children per woman. The total number of births in Brussels is declining. Age of first birth and childbearing The average age of which a mother gives birth has been consistently rising since figures go back to 1998 Age The average age of Brussels is much lower than on average the rest of Belgium. Language Today, the Brussels-Capital Region is legally bilingual, with both French and Dutch having official status, as is the administration of the 19 municipalities. Owing to migration and to its international role, Brussels is home to a large number of native speakers of languages other than French or Dutch. Currently, about half of the population speaks a home language other than these two. In 2013, academic research showed that approximately 17% of families spoke none of the official languages in the home, while in a further 23% a foreign language was used alongside French. The share of unilingual French-speaking families had fallen to 38% and that of Dutch-speaking families to 5%, while the percentage of bilingual Dutch-French families reached 17%. At the same time, French remains widely spoken: in 2013, French was spoken "well to perfectly" by 88% of the population, while for Dutch this percentage was only 23% (down from 33% in 2000); the other most commonly known languages were English (30%), Arabic (18%), Spanish (9%), German (7%) and Italian and Turkish (5% each). Despite the rise of English as a second language in Brussels, including as an unofficial compromise language between French and Dutch, as well as the working language for some of its international businesses and institutions, French remains the lingua franca and all public services are conducted exclusively in French or Dutch. Religion Historically, Brussels has been predominantly Roman Catholic, especially since the expulsion of Protestants in the 16th century. This is clear from the large number of historical churches in the region, particularly in the City of Brussels. The pre-eminent Catholic cathedral in Brussels is the Cathedral of St. Michael and St. Gudula, serving as the co-cathedral of the Archdiocese of Mechelen–Brussels. On the north-western side of the region, the National Basilica of the Sacred Heart is a Minor

https://en.wikipedia.org/wiki/Capacitated%20arc%20routing%20problem
In mathematics, the capacitated arc routing problem (CARP) is that of finding the shortest tour with a minimum graph/travel distance of a mixed graph with undirected edges and directed arcs given capacity constraints for objects that move along the graph that represent snow-plowers, street sweeping machines, or winter gritters, or other real-world objects with capacity constraints. The constraint can be imposed for the length of time the vehicle is away from the central depot, or a total distance traveled, or a combination of the two with different weighting factors. There are many different variations of the CARP described in the book Arc Routing:Problems, Methods, and Applications by Ángel Corberán and Gilbert Laporte. Solving the CARP involves the study of graph theory, arc routing, operations research, and geographical routing algorithms to find the shortest path efficiently. The CARP is NP-hard arc routing problem. The CARP can be solved with combinatorial optimization including convex hulls. The large-scale capacitated arc routing problem (LSCARP) is a variant of the capacitated arc routing problem that applies to hundreds of edges and nodes to realistically simulate and model large complex environments.

In probability theory, a branch of mathematics Poisson-Dirichlet distributions are probability distributions on the set of nonnegative, non-decreasing sequences with sum 1, depending on two parameters and . It can be defined as follows. One considers independent random variables such that follows the beta distribution of parameters and . Then, the Poisson-Dirichlet distribution of parameters and is the law of the random decreasing sequence containing and the products . This definition is due to Jim Pitman and Marc Yor. It generalizes Kingman's law, which corresponds to the particular case . Number theory Patrick Billingsley has proven the following result: if is a uniform random integer in , if is a fixed integer, and if are the largest prime divisors of (with arbitrarily defined if has less than prime factors), then the joint distribution ofconverges to the law of the first elements of a distributed random sequence, when goes to infinity. Random permutations and Ewens's sampling formula The Poisson-Dirichlet distribution of parameters and is also the limiting distribution, for going to infinity, of the sequence , where is the length of the largest cycle of a uniformly distributed permutation of order . If for , one replaces the uniform distribution by the distribution on such that , where is the number of cycles of the permutation , then we get the Poisson-Dirichlet distribution of parameters and . The probability distribution is called Ewens's distribution, and comes from the Ewens's sampling formula, first introduced by Warren Ewens in population genetics, in order to describe the probabilities associated with counts of how many different alleles are observed a given number of times in the sample.

https://en.wikipedia.org/wiki/Mathematics%20in%20Ethiopia
Since ancient times, traditional mathematics in Ethiopia have related to various aspects of astrology, the calendar, and measurements of physical properties such as length, weight, and distance. Ethiopians used alternate units of measurement which differ from fundamental law; traditionally, scaling and counting values have been described using draft animals such as goats, mules, sheep, or camels, and in modern times, steelyards. Measurements Weight Since measurements of weight often require accurate units or standardized scales, they were used less frequently than measurements of capacity (volume) in the past in Ethiopia. Still, there are three basic ways in which weight has been traditionally determined. First, an object's lightness or heaviness could be simply assessed by feel (holding in one's hand) or sight (visual approximation). Second, a basic estimation of weight (such as of a load carried by a porter or draft animal) might be compared to a fundamentally different but familiar unit of another measure, such as the length of a human arm or the volume held in a hand. Third, more accurate comparisons of relative weights were done using scales or other apparatus. Hand measurements were used in many parts of the country to purchase market goods, such as butter. The concepts of load and capacity were often used in lieu of weight when measuring cheap, bulk commodities, such as grain. More sophisticated and accurate techniques were only used for valuable goods such as medicine, gold, and silver. In fact, in the case of gold and silver, weight was essentially considered a concept of value. Load The concept of load—a rough measurement based on the average weight carried by a human porter, donkey, mule, or camel—has long been a widely used unit of weight in traditional Ethiopia, due to its natural emergence from traditional transport. Portuguese Jesuit missionary Manuel de Almeida noted in the 17th century that "the Emperor 'raises ten or twelve thousand loads of provisions' from State lands", while the chronicle of Emperor Iyasu I (r. 1682–1706) "reveals that taxes on trade were likewise largely based on mule and donkey loads". Scales and steelyards The balance has been the most renowned instrument within Ethiopian society. It has various terms in native languages: the Ge'ez word (; plural: ) is first mentioned by the chronicle Emperor Gelawdewos (1540–1559), in which the ruler spent 10,000 of gold for purchase of books. However, the text may be a mistake by a French editor, and actually refer to 10,000 (). Two types of weighting instruments were used. The first was a conventional balance consisting of two equal-length lever arms with two trays: one to hold the object to be weighted and the other to hold a comparison weight. The second was a steelyard balance based on a single tray subtended from a level with unequal arms, the longer arm counteracting the tray. As the more sensitive of the two instruments, steelyards were used to measure t
https://en.wikipedia.org/wiki/Laplace%27s%20approximation
Laplace's approximation provides an analytical expression for a posterior probability distribution by fitting a Gaussian distribution with a mean equal to the MAP solution and precision equal to the observed Fisher information. The approximation is justified by the Bernstein–von Mises theorem, which states that under regularity conditions the posterior converges to a Gaussian in large samples. For example, a (possibly non-linear) regression or classification model with data set comprising inputs and outputs has (unknown) parameter vector of length . The likelihood is denoted and the parameter prior . The joint density of outputs and parameters is the object of inferential desire The joint is equal to the product of the likelihood and the prior and by Bayes' rule, equal to the product of the marginal likelihood and posterior . Seen as a function of the joint is an un-normalised density. In Laplace's approximation we approximate the joint by an un-normalised Gaussian , where we use to denote approximate density, for un-normalised density and is a constant (independent of ). Since the marginal likelihood doesn't depend on the parameter and the posterior normalises over we can immediately identify them with and of our approximation, respectively. Laplace's approximation is where we have defined where is the location of a mode of the joint target density, also known as the maximum a posteriori or MAP point and is the positive definite matrix of second derivatives of the negative log joint target density at the mode . Thus, the Gaussian approximation matches the value and the curvature of the un-normalised target density at the mode. The value of is usually found using a gradient based method, e.g. Newton's method. In summary, we have for the approximate posterior over and the approximate log marginal likelihood respectively. In the special case of Bayesian linear regression with a Gaussian prior, the approximation is exact. The main weaknesses of Laplace's approximation are that it is symmetric around the mode and that it is very local: the entire approximation is derived from properties at a single point of the target density. Laplace's method is widely used and was pioneered in the context of neural networks by David MacKay, and for Gaussian processes by Williams and Barber.

https://en.wikipedia.org/wiki/Kaniadakis%20distribution
In statistics, a Kaniadakis distribution (also known as κ-distribution) is a statistical distribution that emerges from the Kaniadakis statistics. There are several families of Kaniadakis distributions related to different constraints used in the maximization of the Kaniadakis entropy, such as the κ-Exponential distribution, κ-Gaussian distribution, Kaniadakis κ-Gamma distribution and κ-Weibull distribution. The κ-distributions have been applied for modeling a vast phenomenology of experimental statistical distributions in natural or artificial complex systems, such as, in epidemiology, quantum statistics, in astrophysics and cosmology, in geophysics, in economy, in machine learning. The κ-distributions are written as function of the κ-deformed exponential, taking the form enables the power-law description of complex systems following the consistent κ-generalized statistical theory., where is the Kaniadakis κ-exponential function. The κ-distribution becomes the common Boltzmann distribution at low energies, while it has a power-law tail at high energies, the feature of high interest of many researchers.

https://en.wikipedia.org/wiki/List%20of%20PAS%20Giannina%20F.C.%20records%20and%20statistics
This is a list of records and statistics related to the Greek association football Club PAS Giannina F.C. Player records and statistics Most Valuable Players European competitions record During the 2016–17 season, PAS Giannina competed on the UEFA Europa League qualifying rounds for the first time in the club's history. PAS Giannina finished 6th on the 2015–16 Super League Greece, which enabled him to participate, on the Second qualifying round. PAS Giannina first european game On the 21st of July 2016, PAS Giannina faced Odds BK in a full Zosimades Stadium with a total attendance of 5.615 spectators and a one of a kind atmosphere created by the fans, who completed a legendary pre game parade towards the stadium, with thousands of fans and hooligans loudly signing chants. Players were greeted into the stadium by an unprecedented atmosphere which could be heard throughout the whole locality. PAS Giannina captain Alexios Michail opened the score from inside the box after a corner kick taken by Noé Acosta on the 7th minute. PAS Giannina had total control of the game, and in the 31st minute Fonsi Nadales doubled his team lead with a great volley after a perfectly executed cross by Nikos Karanikas. On the second half, the goalkeeper Alexandros Paschalakis with a presice volley across the whole length of the pitch, spotted Dimitrios Ferfelis who took advantage of the opposition's defenders error and sprinted towards goal with Acosta trailing. Ferfelis' shot got blockeded by the goalkeeper, who couldn't handle the ball, and got served for Noé Acosta who scored to form the final score. On the 2nd leg, about 500 PAS Giannina fans traveled to Norway to support their team. The away side managed to concede no goals on the first half, but conceded 3 goals on the second half, and the game was led to extra time. However, the Epirus side managed to score after a remarkable dribble fooling the opposition defenders from Christopher Maboulou, who let the ball pass beside him after a pass from Karanikas, to reach Leonardo Koutris who beat the goalkeeper, and formed the final score of 3-1 after extra time, and eventually led PAS Giannina to the Third qualifying round for the first time in the club's history. Balkans Cup Honours and distinctions Over the years, PAS has competed in the Super League for a total of 25 seasons (plus 2020–21). The club has never won the Super League or the Greek Cup, but it has won lower division titles throughout its history and represented Greece in the 1979–80 and 1993–94 Balkans Cup tournaments. During its history in the Super League, the club finished 3 times in the 5th position (1975–76, 1977–78, 2012–13 seasons) and 3 times in the 6th position (1979–80, 2014–15, 2015–16 seasons). On January 31, 2007, PAS clinched a spot in the Greek Cup semifinals by virtue of an extra-time goal from Evangelos Kontogoulidis before a hostile crowd in Karaiskakis Stadium. With an aggregate score of 3–2, PAS Giannina also is the first ever

https://en.wikipedia.org/wiki/John%20P.%20Vinti
John Pascal Vinti (January 16, 1907, Newport, Rhode Island – September 28, 1990, Boston) was an American theoretical physicist, who published papers not only in physics, but also in mathematics and engineering. He is known for the Vinti integral. Biography His father, Giovanni Giuseppe Vinti (1885–1959), was born in Naples, Italy. In 1922 John P. Vinti graduated from Rogers High School in Newport, Rhode Island. At his high school graduation, he was honored with a prize in scholarship and a prize in mathematics. At age 15 Vinti matriculated at Massachusetts Institute of Technology (MIT). There he graduated with a bachelor's degree in mathematics in 1927 and a Ph.D. in physics in 1932. His thesis Ph.D. thesis is entitled Variational calculation of atomic wave functions. As a postdoc he worked at the University of Pennsylvania from 1932 to 1934 on helium's absorption spectrum. He was from 1934 to 1935 an assistant at MIT, from 1936 to 1937 an instructor at Brown University, from 1937 to 1938 an assistant professor at The Citadel, and from 1939 to 1941 an instructor at Worcester Polytechnic Institute. In 1941 he joined the physics staff of the Ballistics Research Laboratory at Maryland's Aberdeen Proving Ground. There he became chief of the Interior Ballistics Theory Section and a senior physicist (as of 1945). At Aberdeen he developed a keen interest in celestial mechanics and "a close professional relationship with John von Neumann and Maria Goeppert-Mayer." Later in his career, Vinti taught and did research at MIT as a professor in the department of aeronautics and astronautics in the 1970s and 1980s. Lecture notes that Vinti used in a course that he taught in 1966 at the Catholic University of America and later at MIT were posthumously published in 1998 as the book Orbital and Celestial Mechanics, edited by Gim J. Der and Nino L. Bonavito. According to Der and Bonavito, Vinti's spheroidal method was "many years ahead of its time" and "predicts position and velocity vectors for satellites and ballistic missiles almost as accurately as numerical integration." He was elected in 1936 a Fellow of the American Physical Society. Upon his death, John P. Vinti was survived by his sisters, Helena (1908–1995) and Anna (1911–2001), and their children. His nephew Jack Edmonston was his executor and was entrusted with the publication of Orbital and Celestial Mechanics. John P. Vinti is buried in Newton Cemetery in Newton, Massachusetts.

He studies within the fields of algebraic geometry and commutative algebra. His areas of interest in research focus on algebraic cycles, K-theory, Hodge theory, Galois theory, and their interactions. Nori received the INSA Medal for Young Scientists in 1980 and is an elected Fellow of the Indian Academy of Sciences, Bangalore. The fundamental group scheme Under the direction of Conjeerveram S. Seshadri Nori proved the existence of the fundamental group scheme during his PhD work, using the theory of essentially finite vector bundles that he defined. The fundamental group scheme is also known as Nori fundamental group scheme, taking the name by his creator, and often also denoted as , where stands for Nori. There is a special family of vector bundles called Nori-semistable vector bundles in Nori's honor as he had the first intuition for their existence and properties. His construction has been since then further generalized, for istance a proof of the existence of the fundamental group scheme for schemes defined over Dedekind schemes has been provided by Marco Antei, Michel Emsalem and Carlo Gasbarri.

https://en.wikipedia.org/wiki/Nori-semistable%20vector%20bundle
In mathematics, a Nori semistable vector bundle is a particular type of vector bundle whose first definition has been first implicitly suggested by Madhav V. Nori, as one of the main ingredients for the construction of the fundamental group scheme. The original definition given by Nori was obviously not called Nori semistable. Also, Nori's definition was different from the one suggested nowadays. The category of Nori semistable vector bundles contains the Tannakian category of essentially finite vector bundles, whose naturally associated group scheme is the fundamental group scheme . Definition Let be a scheme over a field and a vector bundle on . It is said that is Nori semistable if for any smooth and proper curve over and any morphism the pull back is semistable of degree 0. Difference with Nori's original definition Nori semistable vector bundles were called by Nori semistable causing a lot of confusion with the already existing definition of semistable vector bundles. More importantly Nori simply said that the restriction of to any curve in had to be semistable of degree 0. Then for instance in positive characteristic a morphism like the Frobenius morphism was not included in Nori's original definition. The importance of including it is that the above definition makes the category of Nori semistable vector bundles tannakian and the group scheme associated to it is the -fundamental group scheme . Instead, Nori's original definition didn't give rise to a Tannakian category but only to an abelian category. Notes Scheme theory Topological methods of algebraic geometry

Jean Jacques Bret (25 September 1781 – 29 January 1819) was a French professor of mathematics at the University of Grenoble. He worked on analytical geometry, polynomial roots, and the theory of conics and quadrics. Bret was born in Mercuriol, Drôme, where his father was a notary. He went to study civil engineering at the École Polytechnique in 1800 but was unable to complete studies due to poor health. In 1804 he became a professor of mathematics at the lycée in Grenoble. In 1811 he became a professor at the faculty of science at the University of Grenoble and received a doctorate in 1812. Bret's work was in coordinate geometry, both on the plane and in 3-dimensions. He was among the first to use a parametric form for the line in space. Bret suggested a rule for the superior limits of the roots of polynomial in 1815. The rule has been stated as: "if we add to unity a series of fractions whose numerators are the successive negative coefficients, taken positively, and whose denominators are the sums of the positive coefficients, including that of the first term, the greatest of the resulting values will be a superior limit of the roots of the equation." He also contributed to the study of continued fractions. References 1781 births 1819 deaths French mathematicians
https://en.wikipedia.org/wiki/Equisingularity
In algebraic geometry, an equisingularity is, roughly, a family of singularities that are not non-equivalent and is an important notion in singularity theory. There is no universal definition of equisingularity but Zariki's equisingularity is the most famous one. Zariski's equisingualrity, introduced in 1971 under the name " algebro-geometric equisingularity", gives a stratification that is different from the usual Whitney stratification on a real or complex algebraic variety.

In mathematics, a tame topology is a hypothetical topology proposed by Alexander Grothendieck in his research program Esquisse d’un programme under the French name topologie modérée (moderate topology). It is a topology in which the theory of dévissage can be applied to stratified structures such as semialgebraic or semianalytic sets. Some authors consider an o-minimal structure to be a candidate for realizing tame topology in the real case. There are also some other suggestions.

In 2021, he joined the University of Oxford as a Research Fellow. Research In July 2020, Bloom and Sisask proved that any set such that diverges must contain arithmetic progressions of length 3. This is the first non-trivial case of a conjecture of Erdős postulating that any such set must in fact contain arbitrarily long arithmetic progressions. In November 2020, in joint work with James Maynard, he improved the best-known bound for square-difference-free sets, showing that a set with no square difference has size at most for some . In December 2021, he proved that any set of positive upper density contains a finite  such that . This answered a question of Erdős and Graham.

In mathematics, especially in differential topology, Thom's second isotopy lemma is a family version of Thom's first isotopy lemma; i.e., it states a family of maps between Whitney stratified spaces is locally trivial when it is a Thom mapping. Like the first isotopy lemma, the lemma was introduced by René Thom. gives a sketch of the proof. gives a simplified proof. Like the first isotopy lemma, the lemma also holds for the stratification with Bekka's condition (C), which is weaker than Whitney's condition (B). Thom mapping Let be a smooth map between smooth manifolds and submanifolds such that both have differential of constant rank. Then Thom's condition is said to hold if for each sequence in X converging to a point y in Y and such that converging to a plane in the Grassmannian, we have Let be Whitney stratified closed subsets and maps to some smooth manifold Z such that is a map over Z; i.e., and . Then is called a Thom mapping if the following conditions hold: are proper. is a submersion on each stratum of . For each stratum X of S, lies in a stratum Y of and is a submersion. Thom's condition holds for each pair of strata of . Then Thom's second isotopy lemma says that a Thom mapping is locally trivial over Z; i.e., each point z of Z has a neighborhood U with homeomorphisms over U such that .

https://en.wikipedia.org/wiki/Census%20of%20Sri%20Lanka
The Census of Sri Lanka is a census held by the Sri Lankan Department of Census and Statistics, traditionally taking place every 10 years. The first census of Sri Lanka was taken in 1871, making it the first country in South Asia to conduct a census. The most recent census took place in 2012, the first complete census in the country since 1981 due to disruptions from the Sri Lankan Civil War. History The first census in Sri Lanka was held on 27 March 1871 and conducted by the Registrar General's Office, making it the first of any country in South Asia. It was conducted from then on every ten years. The Census Department was created on 1 December 1944 for taking the Census of 1946, which was postponed from 1941 due to World War II. The Soulbury Constitution of 1947 combined the Department with the Statistics Department to create the Department of Census and Statistics. The 1951 census was postponed to 1953 due to a shortage of paper, and the following was also postponed to 1963. The 1991 census was not held due to the Sri Lankan Civil War (1983–2009), with areas in the Northern and Eastern Provinces controlled by the Tamil militant LTTE. The subsequent 2001 census covered 94% of the country, with no coverage in the Jaffna, Kilinochchi, and Mullaitivu Districts, and only partial coverage in the Vavuniya, Mannar, Batticaloa, and Trincomalee Districts. The following census was held in 2012. The 2021 census was postponed due to the COVID-19 pandemic, and is scheduled to take place in 2023 and 2024. References External links Sri Lanka census

The following tables show the England women's national football team's all-time international record. The statistics are composed of FIFA Women's World Cup and UEFA Women's Championship matches, as well as numerous international friendly tournaments and matches. Following a UEFA recommendation in 1972 for national associations to incorporate the women's game, the Football Association (FA) rescinded its 50-year ban on women playing at English Football League grounds. Shortly after, Eric Worthington was tasked by the Women's Football Association (WFA) to assemble an official women's national team. England competed in its first officially recognised international match against Scotland in Greenock on 18 November 1972, 100 years to the month after the first men's international between the same two nations. England overturned a two-goal deficit to defeat Scotland opponents 3–2, with Sylvia Gore scoring England's first international goal. Prior to this, an English team had played a series of unofficial matches at the 1969 Coppa Europa per Nazioni, and the 1970 and 1971 editions of a "World Championships" held in Italy and Mexico respectively. None of the competitions were sanctioned by FIFA, UEFA, or national associations, and some were contested by club teams acting as de facto national teams. England have contested 464 matches against 53 different national teams. Of these teams, England have not lost to 31 of them, having earned a perfect 100% winning record against 23 of these teams. West Germany is the only team England has played at least one fixture against and never failed to beat having lost both games against them although England has beaten Germany, the team's successor following the reunification of Germany in 1990.

It is an unpublished manuscript in Persian and gives statistics of revenue accounts of the six subas of the Deccan with a historical account of the Asaf Jahis or Nizams of Hyderabad. Munim Khan was a military commander during the regime of Asaf Jah II. This work gave more insight about the regime of Asaf Jahis between 1724 A.D. and 1783 A.D. It also describes the administrative divisions and revenue of the Mughal Deccan during the last years of Aurangzeb's regime. A detailed list of Sarkars, Mahals (Parganas) and Villages along with their revenue was mentioned. The two manuscript copies of this work are preserved in Hyderabad. First one is in Andhra Pradesh State Archives under manuscript number 22 and second one is in Oriental Manuscript Library and Research, Institute. Other resources to know about the administration divisions during the Mughal rule and early Nizam rule were Dastūr-al-amal-e-shāhanshāhi (1781) by Munshī Thākur Lāl, and Deh-be-dehi (c.1705) by Md.

https://en.wikipedia.org/wiki/Mario%20Fiorentini
Mario Fiorentini (7 November 1918 – 9 August 2022) was an Italian partisan, spy, mathematician, and academic, for years a professor of geometry at the University of Ferrara. He engaged in numerous partisan actions, including the assault on the entrance to the Regina Coeli prison and participating in the organization of the attack in via Rasella. He was Italy's most decorated World War II partisan. Biography Youth Fiorentini was born in Rome to Maria Moscatelli and Pacifico Fiorentini on 7 November 1918. His mother, a Catholic, moved to Rome from Cittaducale in search of work, like many other young people at the time; his father, who was Jewish, worked as an accountant and bankruptcy trustee. During the war As a student, Fiorentini collaborated clandestinely with Giustizia e Libertà and with the Communist Party. At the beginning of 1943, he set up with performances at Mazzini Theater and at Delle Arti with actors such as Vittorio Gassman, Lea Padovani, Nora Ricci, Vittorio Caprioli, Carlo Mazzarella, Alberto Bonucci and Ave Ninchi, directed by Luigi Squarzina, Adolfo Celi, and Mario Landi. Later he met , who became his partner. After 25 July 1943, with Antonello Trombadori, he formed a group of partisans known as Arditi del Popolo. On 9 September 1943, Fiorentini took part in the battle against the Germans at Porta San Paolo among the ranks of the members of the Action Party; in October he organized and placed himself in command of the central Patriotic Action Groups (GAP), in the IV operational area "Roma centro", taking the battle name of "John"; this formation, together with the GAP Carlo Pisacane, belonged to the partisan structure belonging to the network commanded by Carlo Salinari. A first GAP action, in which Mario Fiorentini, Rosario Bentivegna (Paolo) and Franco di Lernia (Pietro) took part, was organized to assassinate the Minister of the Interior of Salò Guido Buffarini Guidi and the hierarch Francesco Maria Barracu, intent on dining in a restaurant near Piazza Navona; the action was canceled at the last moment, when the commando was already in place (October 1943). On 31 October, Lucia Ottobrini was added to the three, with cover duties, for an action in Corso Vittorio Emanuele II. The Gappists killed three RSI soldiers, who came out of Palazzo Braschi, after following them almost to Piazza Venezia. His parents were arrested and taken to the military college of Palazzo Salviati, near the Regina Coeli prison during the Raid of the Ghetto of Rome on 16 October 1943, even though they lived outside the ghetto, in via Capo le Case. The two, along with hundreds of other people, were to have been loaded onto trains to be deported but she bribed a guard with the family jewels, thus managing to escape and take refuge with her sister. Mario likewise managed to elude capture that day. He had slept at his parents' home the night before and had bombs hidden under his bed, but was not found because the house was not searched; he escaped by

Education and career Révész was born in Budapest. He studied in the applied mathematics program at the Faculty of Science, Eötvös Loránd University and graduated there in 1957. Afterwards, he got a job at the Eötvös Loránd University's probability department, where he worked as an assistant professor. In 1964, he transferred to the Mathematical Research Institute of the Hungarian Academy of Sciences, where he started working as a scientific associate. In 1963, he defended his candidate's thesis in mathematics, and in 1969 he defended his academic doctoral thesis. He became a member of the Mathematical Committee of the Hungarian Academy of Sciences. He did a significant part of his scientific work here. He was elected a corresponding member of the Hungarian Academy of Sciences in 1982, and a full member in 1987. In 1985, he received a second position as a university professor at the Vienna University of Technology. He left the research institute in 1987, when he was appointed professor at the Institute of Mathematics of the Budapest University of Technology. In Vienna, he also headed the Department of Statistics and Probability, from where he retired in 1998. Between 1999 and 2005, he was the deputy chairman of the Mathematics Department. Meanwhile, he also worked in the Committee on International Relations. Révész became a member of the Academia Europaea in London in 1991. In addition to his academic duties, he also contributed to the management of several scientific societies: from 1983 to 1985 he was the president of the Bernoulli Society of the International Statistical Institute. Between 1995 and 1997, he held the position of acting president of the János Bolyai Mathematical Society. Academic research Révész's main research areas were probability and mathematical statistics. His results related to the so-called strong approximation of stochastic processes and the estimation of the probability density function are significant. He also dealt with statistical applications of the stochastic approximation method. He was the first to provide a method for estimating the regression function that is suitable for simultaneous estimation of all points of the function. He was a close collaborator of Paul Erdős. Honors and awards Révész received the State Award of the People's Republic of Hungary in 1978 for his achievements in probability, especially in the theory of stochastic processes and their practical application. He was an honorary professor at Carleton University and the University of Szeged.

https://en.wikipedia.org/wiki/Wang%20algebra
In algebra and network theory, a Wang algebra is a commutative algebra , over a field or (more generally) a commutative unital ring, in which has two additional properties:(Rule i) For all elements x of , x + x = 0 (universal additive nilpotency of degree 1).(Rule ii) For all elements x of , xx = 0 (universal multiplicative nilpotency of degree 1). History and applications Rules (i) and (ii) were originally published by K. T. Wang (Wang Ki-Tung, 王 季同) in 1934 as part of a method for analyzing electrical networks. From 1935 to 1940, several Chinese electrical engineering researchers published papers on the method. The original Wang algebra is the Grassman algebra over the finite field mod 2. At the 57th annual meeting of the American Mathematical Society, held on December 27–29, 1950, Raoul Bott and Richard Duffin introduced the concept of a Wang algebra in their abstract (number 144t) The Wang algebra of networks. They gave an interpretation of the Wang algebra as a particular type of Grassman algebra mod 2. In 1969 Wai-Kai Chen used the Wang algebra formulation to give a unification of several different techniques for generating the trees of a graph. The Wang algebra formulation has been used to systematically generate King-Altman directed graph patterns. Such patterns are useful in deriving rate equations in the theory of enzyme kinetics. According to Guo Jinhai, professor in the Institute for the History of Natural Sciences of the Chinese Academy of Sciences, Wang Ki Tung's pioneering method of analyzing electrical networks significantly promoted electrical engineering not only in China but in the rest of the world; the Wang algebra formulation is useful in electrical networks for solving problems involving topological methods, graph theory, and Hamiltonian cycles. Wang Algebra and the Spanning Trees of a Graph The Wang Rules for Finding all Spanning Trees of a Graph G For each node write the sum of all the edge-labels that meet that node. Leave out one node and take the product of the sums of labels for all the remaining nodes. Expand the product in 2. using the Wang algebra. The terms in the sum of the expansion obtained in 3. are in 1-1 correspondence with the spanning trees in the graph. References Algebra Electrical engineering Network theory
https://en.wikipedia.org/wiki/Laakso%20space
In mathematical analysis and metric geometry, Laakso spaces are a class of metric spaces which are fractal, in the sense that they have non-integer Hausdorff dimension, but that admit a notion of differential calculus. They are constructed as quotient spaces of where K is a Cantor set. Background Cheeger defined a notion of differentiability for real-valued functions on metric measure spaces which are doubling and satisfy a Poincaré inequality, generalizing the usual notion on Euclidean space and Riemannian manifolds. Spaces that satisfy these conditions include Carnot groups and other sub-Riemannian manifolds, but not classic fractals such as the Koch snowflake or the Sierpiński gasket. The question therefore arose whether spaces of fractional Hausdorff dimension can satisfy a Poincaré inequality. Bourdon and Pajot were the first to construct such spaces. Tomi J. Laakso gave a different construction which gave spaces with Hausdorff dimension any real number greater than 1. These examples are now known as Laakso spaces. Construction We describe a space with Hausdorff dimension . (For integer dimensions, Euclidean spaces satisfy the desired condition, and for any Hausdorff dimension in the interval , where is an integer, we can take the space .) Let be such that Then define K to be the Cantor set obtained by cutting out the middle portion of an interval and iterating that construction. In other words, K can be defined as the subset of containing 0 and 1 and satisfying The space will be a quotient of , where I is the unit interval and is given the metric induced from . To save on notation, we now assume that , so that K is the usual middle thirds Cantor set. The general construction is similar but more complicated. Recall that the middle thirds Cantor set consists of all points in whose ternary expansion consists of only 0's and 2's. Given a string of 0's and 2's, let be the subset of points of K consisting of points whose ternary expansion starts with . For example, Now let be a fraction in lowest terms. For every string a of 0's and 2's of length , and for every point , we identify with the point . We give the resulting quotient space the quotient metric: where each is identified with and the infimum is taken over all finite sequences of this form. In the general case, the numbers b (called wormhole levels) and their orders k are defined in a more complicated way so as to obtain a space with the right Hausdorff dimension, but the basic idea is the same.

In geometry, the dual snub 24-cell is a 144 vertex convex 4-polytope composed of 96 irregular cells. Each cell has faces of two kinds: 3 kites and 6 isosceles triangles. The polytope has a total of 432 faces (144 kites and 288 isosceles triangles) and 480 edges. Geometry The dual snub 24-cell, first described by Koca et al. in 2011, is the dual polytope of the snub 24-cell, a semiregular polytope first described by Thorold Gosset in 1900. Construction The vertices of a dual snub 24-cell are obtained using quaternion simple roots (T') in the generation of the 600 vertices of the 120-cell. The following describe and 24-cells as quaternion orbit weights of D4 under the Weyl group W(D4): O(0100) : T = {±1,±e1,±e2,±e3,(±1±e1±e2±e3)/2} O(1000) : V1 O(0010) : V2 O(0001) : V3 With quaternions where is the conjugate of and and , then the Coxeter group is the symmetry group of the 600-cell and the 120-cell of order 14400. Given such that and as an exchange of within where is the golden ratio, we can construct: the snub 24-cell the 600-cell the 120-cell the alternate snub 24-cell and finally the dual snub 24-cell can then be defined as the orbits of .

Frederick Ronald Cohen (1945 – January 16, 2022) was an American mathematician working in algebraic topology. Education and career Fred Cohen was born in 1945 in Chicago. He received a BA from Brandeis University in 1967 and a PhD from the University of Chicago in 1972. He taught at the University of Northern Illinois until 1979 and then at the University of Kentucky. In 1989, he settled at the University of Rochester, where he spent the rest of his career. Mathematics Cohen did influential work in several areas of homotopy theory. His thesis concerned the topology of configuration spaces, a topic he came back to throughout his life, with connections to braid groups and mapping class groups. This was followed by a series of influential papers on unstable homotopy groups of spheres with John Moore and Joseph Neisendorfer. Late in his life, Cohen studied polyhedral products in a series of articles with Bahri, Bendersky, and Gitler. Selected publications Personal life In the late 1970's, Cohen battled a spinal tumor. Although he survived with the help of radiation therapy, he was partially paralyzed for the rest of his life. Starting in 2013, he used a wheelchair. Cohen was survived by his wife Kathleen and two daughters.

In algebraic topology, a branch of mathematics, the path space of a based space is the space that consists of all maps from the interval to X such that , called paths. In other words, it is the mapping space from to . The space of all maps from to X (free paths or just paths) is called the free path space of X. The path space can then be viewed as the pullback of along . The natural map is a fibration called the path space fibration.

In mathematics, the category of compactly generated weak Hausdorff spaces CGWH is one of typically used categories in algebraic topology as a substitute for the category of topological spaces, as the latter lacks some of the pleasant properties one would desire. There is also such a category for based spaces, defined by requiring maps to preserve the base points. The articles compactly generated space and weak Hausdorff space define the respective topological properties. For the historical motivation behind these conditions on spaces, see Compactly generated space#Motivation. This article focuses on the properties of the category. Properties CGWH has the following properties: It is complete and cocomplete. The forgetful functor to the sets preserves small limits. It contains all the locally compact Hausdorff spaces and all the CW complexes. The internal Hom exists for any pairs of spaces X, Y; it is denoted by or and is called the (free) mapping space from X to Y. Moreover, there is a homeomorphism that is natural in X, Y, Z. In short, the category is Cartesian closed in an enriched sense. A finite product of CW complexes is a CW complex. If X, Y are based spaces, then the smash product of them exists. The (based) mapping space from X to Y consists of all base-point-preserving maps from X to Y and is a closed subspace of the mapping space between the underlying unbased spaces. It is a based space with the base point the unique constant map. For based spaces X, Y, Z, there is a homeomorphism that is natural in X, Y, Z.

https://en.wikipedia.org/wiki/Semisimple%20element
In mathematics, a semisimple element is an abstract element of an algebraic structure that generalizes a diagonalizable matrix. A precise meaning depends on context: A semisimple element in the endomorphism ring of a vector space is a semisimple operator. In a semisimple Lie algebra, an element is semisimple if its image under the adjoint representation is semisimple; see Semisimple Lie algebra#Jordan decomposition.
