https://en.wikipedia.org/wiki/Lynne%20Butler | Lynne Marie Butler (born 1959) is an American mathematician whose research interests include algebraic combinatorics, group theory, and mathematical statistics. She is a professor of mathematics at Haverford College.
Early life and education
Butler's parents were both medical professionals. She is the identical twin sister of Laurie Butler, now a professor of chemistry at the University of Chicago; they were the youngest of six siblings, and grew up in Garden City, New York. After Butler's father had a stroke, the family moved to St. Petersburg, Florida, where Butler went to high school. She credits a high school mathematics teacher, Mr. Mead, for sparking her interest in mathematics, writing "He wanted to learn group theory, and so did I, so we learned together."
Butler majored in mathematics at the University of Chicago, graduating in 1981. She went to the Massachusetts Institute of Technology for doctoral study in mathematics, intending to work in algebraic topology despite warnings about the professor she would be working with from other women in the department. He thought that the prospect of marriage and children would make women unable to concentrate on mathematics, refused to let her read his recent work, and eventually told her that her difficulty in reading a paper "confirmed his bad opinion of female mathematicians". On the advice of the department chair, in order to avoid the possibility that her former advisor would be asked to recommend her, she changed her research topic. Instead, she began working in combinatorics with Richard P. Stanley as her new advisor. She completing her Ph.D. in 1986.
In 2013, bored with combinatorics and noting that many of her female students were doing particularly well the application-oriented components of her classes, she returned to the University of Chicago for a master's degree in statistics.
Career
After completing her doctorate, Butler became a postdoctoral researcher and then, a year later, an assistant professor at Princeton University. However, at Princeton she encountered much of the same explicit sexism that had tormented her at MIT. One faculty member in her department assumed she was a secretary and handed secretarial work to her, and she was the target of comments about the incompatibility of child-bearing with mathematics, or remarks to her like "I really do feel women are genetically inferior in math", to the point that she says she "locked myself in my office and didn't come out for four years".
Despite marrying Princeton computer scientist F. Miller Maley, she moved in 1991 from Princeton to Haverford College, where she had a potential collaborator on the faculty and could find a more collegial atmosphere.
She became a full professor at Haverford in 1996, the same year in which she was a visiting research professor at the Mathematical Sciences Research Institute. At Haverford, she has served several terms as department chair, and was associate provost for 2004–2005.

https://en.wikipedia.org/wiki/Discrete%20calculus | Discrete calculus or the calculus of discrete functions, is the mathematical study of incremental change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations. The word calculus is a Latin word, meaning originally "small pebble"; as such pebbles were used for calculation, the meaning of the word has evolved and today usually means a method of computation. Meanwhile, calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the study of continuous change.
Discrete calculus has two entry points, differential calculus and integral calculus. Differential calculus concerns incremental rates of change and the slopes of piece-wise linear curves. Integral calculus concerns accumulation of quantities and the areas under piece-wise constant curves. These two points of view are related to each other by the fundamental theorem of discrete calculus.
The study of the concepts of change starts with their discrete form. The development is dependent on a parameter, the increment of the independent variable. If we so choose, we can make the increment smaller and smaller and find the continuous counterparts of these concepts as limits. Informally, the limit of discrete calculus as is infinitesimal calculus. Even though it serves as a discrete underpinning of calculus, the main value of discrete calculus is in applications.
Two initial constructions
Discrete differential calculus is the study of the definition, properties, and applications of the difference quotient of a function. The process of finding the difference quotient is called differentiation. Given a function defined at several points of the real line, the difference quotient at that point is a way of encoding the small-scale (i.e., from the point to the next) behavior of the function. By finding the difference quotient of a function at every pair of consecutive points in its domain, it is possible to produce a new function, called the difference quotient function or just the difference quotient of the original function. In formal terms, the difference quotient is a linear operator which takes a function as its input and produces a second function as its output. This is more abstract than many of the processes studied in elementary algebra, where functions usually input a number and output another number. For example, if the doubling function is given the input three, then it outputs six, and if the squaring function is given the input three, then it outputs nine. The derivative, however, can take the squaring function as an input. This means that the derivative takes all the information of the squaring function—such as that two is sent to four, three is sent to nine, four is sent to sixteen, and so on—and uses this information to produce another function. The function produced by differentiating the squaring function turns out to be something close to the doubling function.

https://en.wikipedia.org/wiki/Character%20module | In mathematics, especially in the area of abstract algebra, every module has an associated character module. Using the associated character module it is possible to investigate the properties of the original module. One of the main results discovered by Joachim Lambek shows that a module is flat if and only if the associated character module is injective.
Definition
The group , the group of rational numbers modulo , can be considered as a -module in the natural way. Let be an additive group which is also considered as a -module. Then the group of -homomorphisms from to is called the character group associated to . The elements in this group are called characters. If is a left -module over a ring , then the character group is a right -module and called the character module associated to . The module action in the character module for and is defined by for all . The character module can also be defined in the same way for right -modules. In the literature also the notations and are used for character modules.
Let be left -modules and an -homomorphismus. Then the mapping defined by for all is a right -homomorphism. Character module formation is a contravariant functor from the category of left -modules to the category of right -modules.
Motivation
The abelian group is divisible and therefore an injective -module. Furthermore it has the following important property: Let be an abelian group and nonzero. Then there exists a group homomorphism with . This says that is a cogenerator. With these properties one can show the main theorem of the theory of character modules: Theorem (Lambek): A left module over a ring is flat if and only if the character module is an injective right -module.
Properties
Let be a left module over a ring and the associated character module.
The module is flat if and only if is injective (Lambek's Theorem).
If is free, then is an injective right -module and is a direct product of copies of the right -modules .
For every right -module there is a free module such that is isomorphic to a submodule of . With the previous property this module is injective, hence every right -module is isomorphic to a submodule of an injective module. (Baer's Theorem)
A left -module is injective if and only if there exists a free such that is isomorphic to a direct summand of .
The module is injective if and only if it is a direct summand of a character module of a free module.
If is a submodule of , then is isomorphic to the submodule of which consists of all elements which annihilate .
Character module formation is a contravariant exact functor, i.e. it preserves exact sequences.
Let be a right -module. Then the modules and are isomorphic as -modules.

Education and career
Aftalion studied at the École normale supérieure (Paris) from 1992 to 1996, earning her agrégation in mathematics in 1994 and Master of Advanced Studies in numerical analysis in 1995. She defended her doctoral dissertation, Quelques problèmes d'équations aux dérivées partielles elliptiques non linéaires et applications à des modèles en supraconductivité et en combustion, in 1997 at Pierre and Marie Curie University, under the direction of Henri Berestycki. In 2002 she earned a habilitation with the thesis Equations aux dérivées partielles elliptiques non linéaires : propriétés qualitatives et modèles en physique des basses températures.
She has been a researcher with CNRS since 1999, and was promoted to director of research in 2008. Since 2010 her position with CNRS has been associated with Versailles Saint-Quentin-en-Yvelines University.
Contributions
Aftalion is the author of the book Vortices in Bose–Einstein Condensates (Birkhäuser, 2006). The book studies quantum vortex and superfluid behavior in Bose–Einstein condensates, using the Gross–Pitaevskii equation to model the energy in these systems.
In her research on the mathematics of sports, Aftalion uses differential equations to model both the motion and forces on a runner, and the aerobic and anaerobic fitness of the runner as a race progresses.
She has used the theory of optimal control to show that long-distance runners can achieve greater endurance by small variations in speed, contradicting earlier research by Joseph Keller suggesting that runners should keep their speed nearly constant throughout a race. In follow-on work, she showed that, although long-distance runners should speed up in the final sprint of a race, the optimal strategy for a short footrace involves slowing down towards the end of the race.

https://en.wikipedia.org/wiki/Jean-Marc%20Vanden-Broeck | Jean-Marc Vanden-Broeck (born 11 September 1951) is a UK mathematician of Belgian origin. He is a Professor of Applied Mathematics at the University College, London.
Early life and education
Vanden-Broeck was born in Liège, Belgium on 11 September 1951. He received a degree in engineering and physics from the University Of Liège in 1974 and another one in oceanology in 1975. He then became a Ph.D. student at the University of Adelaide, Australia, where he worked with Ernie Tuck and Leonard Schwartz. His Ph.D. thesis entitled Two-dimensional nonlinear free surface flows past semi-infinite bodies, was defended in 1978 and received the William Culross Prize for Scientific Research.
Academic career
After a short postdoctoral experience in Australia, Vanden-Broeck moved to the United States, first as a Senior Researcher at the Courant Institute, New York, 1978-1979, and then in a similar post at the Stanford University 1979-1981. There he started a fruitful collaboration with Joseph B Keller. He then moved to the University of Wisconsin-Madison, where he became a full professor in 1987. Vanden-Broeck stayed at the University of Wisconsin-Madison until 1998, when he returned to Europe, taking the post of the Professor of Applied Mathematics at the University of East Anglia in Norwich, England. In 2007 he moved to University College London, where he is a Professor of Applied Mathematics.
In addition to the posts listed above, Vanden-Broeck has held visiting professorship at a number of universities around the world, including a visiting professorship at the Tel Aviv University, Israel 1993-1994, Weisman Visiting Professorship at Baruch College in 2001 and Chair Montel at the University of Nice, France in 2019. Since 1999 he has been a Research Professor at New Jersey Institute of Technology. Vanden-Broeck has had many graduate students, some of whom are Ersin Ozugurlu, Ben Binder, Tao Gao and Alex Doak, and has mentored and co-mentored numerous postdocs, including Emilian Parau, Dmitri Tseluiko, Zhan Wang and Olga Tritchtchenko.
Vanden-Broeck shares his life between London and Paris. He is married to the logician Mirna Dzamonja. They have a daughter, Ada Vanden-Broeck, who was born in 2006.
Scientific work
Vanden-Broeck works on Applied Mathematics, Fluid Mechanics and Scientific Computing. He is known for his work on free boundary problems. These problems involve solving partial differential equations in domains whose shape has to be found as part of the solution. They occur in applications, such as waves propagating at the interface between two fluids, bubbles rising in a fluid and growing tumours. Mathematically, free boundary problems are challenging because of their nonlinearity. He has developed efficient and accurate boundary integral equation methods to solve free boundary problems occurring in fluid mechanics.
An important insight of this work is the effect of surface tension, where he discovered classes of problems which have a contin |

https://en.wikipedia.org/wiki/Kummer%27s%20transformation%20of%20series | In mathematics, specifically in the field of numerical analysis, Kummer's transformation of series is a method used to accelerate the convergence of an infinite series. The method was first suggested by Ernst Kummer in 1837.
Technique
Let
be an infinite sum whose value we wish to compute, and let
be an infinite sum with comparable terms whose value is known.
If the limit
exists, then is always also a sequence going to zero and the series given by the difference, , converges.
If , this new series differs from the original and, under broad conditions, converges more rapidly.
We may then compute as
,
where is a constant. Where , the terms can be written as the product .
If for all , the sum is over a component-wise product of two sequences going to zero,
.
Example
Consider the Leibniz formula for π:
We group terms in pairs as
where we identify
.
We apply Kummer's method to accelerate , which will give an accelerated sum for computing .
Let
This is a telescoping series with sum value .
In this case
and so Kummer's transformation formula above gives
which converges much faster than the original series.
Coming back to Leibniz formula, we obtain a representation of that separates and involves a fastly converging sum over just the squared even numbers ,

https://en.wikipedia.org/wiki/Clare%20Parnell | Clare Elizabeth Parnell (born 1970) is a British astrophysicist and applied mathematician who studies the mathematics of the sun and of magnetic fields, including the Solar corona and the sun's magnetic carpet, magnetic reconnection in plasma, and the null points of magnetic fields. She is a professor of mathematics at the University of St Andrews, and the former head of the Division of Applied Mathematics at St Andrews.
Education and career
Parnell was born in Essex and educated at The Ridgeway School and Swindon Technical College. As a child, she found mathematics to be her easiest subject. She entered the University of Wales College Cardiff in 1988, originally intending to study both chemistry and mathematics, but after a year switched to mathematics only.
In 1991 she completed a bachelor's degree with first class honours in mathematics at Cardiff. She then came to the University of St Andrews as a doctoral student, finishing her Ph.D. in theoretical solar physics in 1994.
She remained at St Andrews as a postdoctoral researcher (interrupted by research at Stanford University in 1996–1997), became a lecturer in 2002, and was promoted to professor in 2011. From 2009 to 2013 she was head of the Division of Applied Mathematics at St Andrews.
Recognition
In 2006, Parnell won the Fowler Prize for Early Achievement in Astronomy and Geophysics of the Royal Astronomical Society for her research on how the Solar corona is heated. In 2007 she won a Philip Leverhulme Prize for her work on solar physics.
Personal
Parnell is an avid mountaineer and chose the University of Wales in part for its nearby mountains. In her three years as a doctoral student at St Andrews, she climbed all 277 peaks then listed as Munros. She has two children.

https://en.wikipedia.org/wiki/Morley%E2%80%93Wang%E2%80%93Xu%20element | In applied mathematics, the Morlely–Wang–Xu (MWX) element is a canonical construction of a family of piecewise polynomials with the minimal degree elements for any -th order of elliptic and parabolic equations in any spatial-dimension for . The MWX element provides a consistent approximation of Sobolev space in .
Morley–Wang–Xu element
The Morley–Wang–Xu element is described as follows. is a simplex and . The set of degrees of freedom will be given next.
Given an -simplex with vertices , for , let be the set consisting of all -dimensional subsimplexe of . For any , let denote its measure, and let be its unit outer normals which are linearly independent.
For , any -dimensional
subsimplex and with , define
The degrees of freedom are depicted in Table 1. For , we obtain the well-known conforming linear element. For and , we obtain the well-known nonconforming Crouziex–Raviart element. For , we recover the well-known Morley element for and its generalization to . For , we obtain a new cubic element on a simplex that has 20 degrees of freedom.
Generalizations
There are two generalizations of Morley–Wang–Xu element (which requires ).
: Nonconforming element
As a nontrivial generalization of Morley–Wang–Xu elements, Wu and Xu propose a universal construction for the more difficult case in which . Table 1 depicts the degrees of freedom for the case that . The shape function space is , where is volume bubble function. This new family of finite element methods provides practical discretization methods for, say, a sixth order elliptic equations in 2D (which only has 12 local degrees of freedom). In addition, Wu and Xu propose an nonconforming finite element that is robust for the sixth order singularly perturbed problems in 2D.
: Interior penalty nonconforming FEMs
An alternative generalization when is developed by combining the interior penalty and nonconforming methods by Wu and Xu. This family of finite element space consists of piecewise polynomials of degree not greater than . The degrees of freedom are carefully designed to preserve the weak-continuity as much as possible. For the case in which , the corresponding interior penalty terms are applied to obtain the convergence property. As a simple example, the proposed method for the case in which is to find , such that

https://en.wikipedia.org/wiki/Numberphile | Numberphile is an educational YouTube channel featuring videos that explore topics from a variety of fields of mathematics. In the early days of the channel, each video focused on a specific number, but the channel has since expanded its scope, featuring videos on more advanced mathematical concepts such as Fermat's Last Theorem, the Riemann hypothesis and Kruskal's tree theorem. The videos are produced by Brady Haran, a former BBC video journalist and creator of Periodic Videos, Sixty Symbols, and several other YouTube channels. Videos on the channel feature several university professors, maths communicators and famous mathematicians.
In 2018, Haran released a spin-off audio podcast titled The Numberphile Podcast.
YouTube channel
The Numberphile YouTube channel was started on 15 September 2011. Most videos consist of Haran interviewing an expert on a number, mathematical theorem or other mathematical concept. The expert usually draws out their explanation on a large piece of brown paper and attempts to make the concepts understandable to the average, non-mathematician viewer. It is supported by the Mathematical Sciences Research Institute (MSRI) and Math for America. Haran also runs the "Numberphile2" channel, which includes extra footage and further detail than the main channel.
Reception
Numberphile consistently rates among the top YouTube channels in math and education. The channel was nominated for a Shorty Award in Education in 2016. The New York Times said that, "at Numberphile, mathematicians discourse, enthusiastically and winningly, on numbers", and The Independent described the channel as "insanely popular". The Sunday Times said, "The mathematical stars of social media, such as James Grime and Matt Parker, entertain legions of fans with glorious videos demonstrating how powerful and playful maths can be."
New Scientist listed Numberphile as one of the top ten science channels on YouTube in 2019.

It is a part of the Iberville Parish School Board and serves the portion of the parish on the west bank of the Mississippi River, which is the more populated section.
1,300 students were enrolled at MSA West. Circa 2013 a renovation of $20 million was scheduled. At the time residents on the east bank complained that their schools were not getting renovations, while the leadership of the district argued that the school had four times the enrollment of MSA East and therefore needed more funding allocated to its renovation.

https://en.wikipedia.org/wiki/Tilla%20Weinstein | Tilla Weinstein (1934–2002, née Savanuck, also published as Tilla Klotz and Tilla K. Milnor) was an American mathematician known for her mentorship of younger women in mathematics. Her research concerned differential geometry, including conformal structures, harmonic maps, and Lorentz surfaces. She taught for many years at Rutgers University, where she headed the mathematics department in the Douglass Residential College.
Early life and education
Weinstein was born as Tilla Savanuck, in 1934. Her father was a Russian immigrant and lawyer in New York City; her mother was a legal secretary. She began her undergraduate studies in 1951 as an English major at the University of Michigan, in part to get away from her parents' rocky marriage and to live near relatives in Detroit. There, her courses included calculus from Hans Samelson and a course in the foundations of mathematics from Raymond Louis Wilder.
After her first year in Michigan, she became engaged to an English student she knew in New York, and after her second year (in 1953), she married him and returned to New York. Not wishing to repeat her earlier coursework (as she would if she had transferred to the City College of New York), she became a mathematics undergraduate student at New York University. She was the only woman in the program at the time.
After her marriage, she used the name Tilla Klotz for her publications, a name she would continue to use until the late 1960s.
At NYU, her calculus instructor, Jean van Heijenoort, noted her ability, encouraged her to participate in the school's team for the William Lowell Putnam Mathematical Competition, and led her to take advanced classes in mathematics, including a class in complex analysis from Lipman Bers. In her first meeting with Bers, she announced her pregnancy, but Bers was supportive and helped her to complete her bachelor's degree "without undue delay", despite opposition from the dean of the school. She completed her Ph.D. in 1959 at NYU. Her dissertation, On G. Bol's Proof of Caratheodory's Conjecture, was supervised by Bers.
Career and later life
Although Bers found a position for Weinstein at the University of California, Berkeley, she was unable to find a matching position for her husband, and declined the offer. With the assistance of Bers, she instead became a faculty member at the University of California, Los Angeles, and earned tenure there in 1966, the first woman to earn tenure in the mathematics department there.
After a "sudden and unexpected" divorce in the late 1960s, she married Princeton mathematician John Milnor (also recently divorced) in 1968, and changed her name on her publications to Tilla K. Milnor, a name she continued to use until 1991. She moved in 1969 to Boston College, in order to be less far from her husband, who was working in Princeton, New Jersey.
In 1970, Weinstein was hired by Rutgers University to become the chair of the mathematics department in the Douglass Residential College. She serv |

Her research specialties include complex geometry, Fuchsian groups, Riemann surfaces, and abelian varieties.
Education
Rodríguez earned a master's degree in mathematics at the in 1975. She completed her Ph.D. in 1981 at Columbia University; her dissertation, On Schottky-Type Groups with Applications to Riemann Surfaces with Nodes, was supervised by Lipman Bers.
Career
Rodríguez worked for the University of Santiago, Chile, but was dismissed in 1985, during the regime of Augusto Pinochet, for unstated but likely-political reasons. After many colleagues appealed the decision, she was hired by the Federico Santa María Technical University.
She was president of the Chilean Mathematical Society from 2006 to 2010.
Books
Rodríguez is the co-author of the book Complex Analysis: In the Spirit of Lipman Bers (Graduate Texts in Mathematics, 2007, 2nd ed., 2013, with Irwin Kra and Jane Piore Gilman). She is the co-editor of Lipman Bers, a Life in Mathematics (American Mathematical Society, 2015, with Linda Keen and Irwin Kra).

https://en.wikipedia.org/wiki/Federico%20Rodriguez%20Hertz | Federico Rodríguez Hertz (born December 14, 1973) is a mathematician working in the United States of Argentinian origin. He is the Anatole Katok Chair professor of mathematics at Penn State University. Rodriguez Hertz studies dynamical systems and ergodic theory, which can be used to described chaos's behaviors over the large time scale and also has many applications in statistical mechanics, number theory, and geometry.
Early life and education
He is the son of Mariana Frugoni and Adolfo Rodriguez Hertz. He has four siblings, including Jana, a mathematician, teacher and researcher.
Rodriguez Hertz studied at the Universidad Nacional de Rosario in Argentina as an undergraduate student. He moved to Montevideo, Uruguay in 1995, and, unable to continue studies there, he moved in 1996 to Rio de Janeiro where he studied at the graduate school at IMPA and earned a doctoral degree at the IMPA in Brazil in 2001 (with a thesis on "Stable Ergodicity of Toral Automorphisms" under Jacob Palis, Jr.). His doctoral thesis was published in the Annals of Mathematics and made a breakthrough in this field. After he received his Ph.D., he moved back to Uruguay, where worked at the National University until moving to Penn State.
Work and research
Rodriguez Hertz has published research papers in journals including Annals of Mathematics, Acta Mathematica, Journal of the American Mathematical Society, Inventiones Mathematicae, Contemporary Mathematics, and Journal of Modern Dynamics.
The first important contribution of Federico Rodriguez Hertz is his thesis dealing with stable ergodicity, which established the tools for proving stable ergodicity of non accessible systems. Then jointly with Jana Rodriguez Hertz, Ali Tahzibi and Raul Ures, Federico Rodriguez Hertz has proved a series of deep results about the geometry of Hopf brushes. It has been commented that his work "allows one to bring to the spotlight new powerful tools of rigidity theory, in particular topological and geometric methods." Later, Rodriguez Hertz has researched rigidity theory, which describes the flexibility and motion of sets of rigid bodies. His work in nonuniform-measure rigidity has advanced ergodic theory. A recent work of Aaron Brown and Federico Rodriguez Hertz provides a significant generalization of nonuniform-measure rigidity theory. Another very important work of Rodriguez Hertz is on global rigidity of Anosov actions, joint with Zhiren Wang and joint with Aaron Brown and Zhiren Wang, which has been seen as "the crowning achievements in the work on global rigidity of Anosov actions on tori and nilmanifolds".
Federico Rodriguez Hertz is an editor of the Journal of Modern Dynamics. He has served as a referee for many distinguished peer-reviewed journals, including Annals of Mathematics and Inventiones Mathematicae, and as an evaluator for the Fondo Nacional de Desarrollo Cientifico y Tecnologico, a research foundation promoting science and technology in Chile.

https://en.wikipedia.org/wiki/Exsymmedian | In Euclidean geometry, the exsymmedians are three lines associated with a triangle. More precisely, for a given triangle the exsymmedians are the tangent lines on the triangle's circumcircle through the three vertices of the triangle. The triangle formed by the three exsymmedians is the tangential triangle; its vertices, that is the three intersections of the exsymmedians, are called exsymmedian points.
For a triangle with being the exsymmedians and being the symmedians through the vertices , two exsymmedians and one symmedian intersect in a common point:
The length of the perpendicular line segment connecting a triangle side with its associated exsymmedian point is proportional to that triangle side. Specifically the following formulas apply:
Here denotes the area of the triangle , and denote the perpendicular line segments connecting the triangle sides with the exsymmedian points .

https://en.wikipedia.org/wiki/Hand%E2%80%93eye%20calibration%20problem | In robotics and mathematics, the hand–eye calibration problem (also called the robot–sensor or robot–world calibration problem) is the problem of determining the transformation between a robot end-effector and a sensor or sensors (camera or laser scanner) or between a robot base and the world coordinate system. It is conceptually analogous to biological hand–eye coordination (hence the name). It takes the form of , where A and B are two systems, usually a robot base and a camera, and and are unknown transformation matrices. A highly studied special case of the problem occurs where , taking the form of the problem . Solutions to the problem take the forms of several types of methods, including separable closed-form solutions, simultaneous closed-form solutions, and iterative solutions. The covariance of in the equation can be calculated for any randomly perturbed matrices and .
The problem is an important part of robot calibration, with efficiency and accuracy of the solutions determining the speed accuracy of the calibrations of robots.
Methods
Many different methods and solutions developed to solve the problem, broadly defined as either separable, simultaneous solutions. Each type of solution has specific advantages and disadvantages as well as formulations and applications to the problem. A common theme throughout all of the methods is the common use of quaternions to represent rotations.
Separable solutions
Given the equation , it is possible to decompose the equation into a purely rotational and translational part; methods utilizing this are referred to as separable methods. Where represents a 3×3 rotation matrix and a 3×1 translation vector, the equation can be broken into two parts:
The second equation becomes linear if is known. As such, the most frequent approach is to solve for and using the first equation, then using to solve for the variables in the second equation. Rotation is represented using quaternions, allowing for a linear solution to be found. While separable methods are useful, any error in the estimation for the rotation matrices is compounded when being applied to the translation vector. Other solutions avoid this problem.
Simultaneous solutions
Simultaneous solutions are based on solving for both and at the same time (rather than basing the solution of one part off of the other as in separable solutions), propagation of error is significantly reduced. By formulating the matrices as dual quaternions, it is possible to get a linear equation by which is solvable in a linear format. An alternative way applies the least-squares method to the Kronecker product of the matrices . As confirmed by experimental results, simultaneous solutions have less error than separable quaternion solutions.
Iterative solutions
Iterative solutions are another method used to solve the problem of error propagation. One example of an iterative solution is a program based on minimizing . As the program iterates, it will converge on a |
https://en.wikipedia.org/wiki/Lepage%20test | In statistics, the Lepage test is an exact distribution-free test (nonparametric test) for jointly monitoring the location (central tendency) and scale (variability) in two-sample treatment versus control comparisons. This is one of the most famous rank tests for the two-sample location-scale problem. The Lepage test statistic is the squared Euclidean distance of standardized Wilcoxon rank-sum test for location and the standardized Ansari–Bradley test for scale. The Lepage test was first introduced by Yves Lepage in 1971 in a paper in Biometrika. A large number of Lepage-type tests exists in statistical literature for simultaneously testing location and scale shifts in case-control studies. The details may be found in the book: Nonparametric statistical tests: A computational approach. Kössler, W. in 2006 also introduced various Lepage type tests using some alternative score functions optimal for various distributions. Dr. Amitava Mukherjee and Dr. Marco Marozzi introduced a class of percentile modified version of the Lepage test. An alternative to the Lepage-type tests is known as the Cucconi test proposed by Odoardo Cucconi in 1968.
Conducting the Lepage test with R, an open-source software
Practitioners can apply the Lepage test using the pLepage function of the contributory package NSM3, built under R software. Andreas Schulz and Markus Neuhäuser also provided detailed R code for computation of test statistic and p-value of the Lepage test for the users.
Application in statistical process monitoring
In recent years, Lepage statistic is widely used statistical process monitoring and quality control. In a classical development, in 2012, Amitava Mukherjee, an Indian statistician, and Subhabrata Chakraborti, an American statistician of Indian origin, introduced a distribution-free Shewhart-type Phase-II monitoring scheme (control chart) for simultaneously monitoring of location and scale parameter of a process using a test sample of fixed size, when a reference sample of sufficiently large size is available from an in-control population. Later in 2015, the same statisticians along with Shovan Chowdhury, proposed a distribution-free CUSUM-type Phase-II monitoring scheme based on the Lepage statistic. In 2017, Mukherjee further designed an EWMA-type distribution-free Phase-II monitoring scheme for joint monitoring of location and scale. In the same year, Mukherjee, with Marco Marozzi, an Italian statistician known for promoting the Cucconi test, came together to design Circular-Grid Lepage chart – a new type of joint monitoring scheme.
Multisample version of the Lepage test
In 2005, František Rublìk introduced the multisample version of the original two-sample Lepage test. This work recently emerge as the motivation behind the proposal of the Phase-I distribution-free Shewhart-type control chart for joint monitoring of location and scale.

https://en.wikipedia.org/wiki/Closed%20graph%20property | In mathematics, particularly in functional analysis and topology, closed graph is a property of functions.
A function between topological spaces has a closed graph if its graph is a closed subset of the product space .
A related property is open graph.
This property is studied because there are many theorems, known as closed graph theorems, giving conditions under which a function with a closed graph is necessarily continuous. One particularly well-known class of closed graph theorems are the closed graph theorems in functional analysis.
Definitions
Graphs and set-valued functions
Definition and notation: The graph of a function is the set
.
Notation: If is a set then the power set of , which is the set of all subsets of , is denoted by or .
Definition: If and are sets, a set-valued function in on (also called a -valued multifunction on ) is a function with domain that is valued in . That is, is a function on such that for every , is a subset of .
Some authors call a function a set-valued function only if it satisfies the additional requirement that is not empty for every ; this article does not require this.
Definition and notation: If is a set-valued function in a set then the graph of is the set
.
Definition: A function can be canonically identified with the set-valued function defined by for every , where is called the canonical set-valued function induced by (or associated with) .
Note that in this case, .
Open and closed graph
We give the more general definition of when a -valued function or set-valued function defined on a subset of has a closed graph since this generality is needed in the study of closed linear operators that are defined on a dense subspace of a topological vector space (and not necessarily defined on all of ).
This particular case is one of the main reasons why functions with closed graphs are studied in functional analysis.
Assumptions: Throughout, and are topological spaces, , and is a -valued function or set-valued function on (i.e. or ). will always be endowed with the product topology.
Definition: We say that has a closed graph (resp. open graph, sequentially closed graph, sequentially open graph) in if the graph of , , is a closed (resp. open, sequentially closed, sequentially open) subset of when is endowed with the product topology. If or if is clear from context then we may omit writing "in "
Observation: If is a function and is the canonical set-valued function induced by (i.e. is defined by for every ) then since , has a closed (resp. sequentially closed, open, sequentially open) graph in if and only if the same is true of .

https://en.wikipedia.org/wiki/Emilie%20Virginia%20Haynsworth | Emilie Virginia Haynsworth (June 1, 1916 – May 4, 1985) was an American mathematician at Auburn University who worked in linear algebra and matrix theory. She gave the name to Schur complements and is the namesake of the Haynsworth inertia additivity formula. She was known for the "absolute originality" of her mathematical formulations, her "strong and independent mind", her "fine sense of mathematical elegance", and her "strong mixture of the traditional and unconventional".
Education and career
Haynsworth was born and died in Sumter, South Carolina. She competed in mathematics at the statewide level in junior high school, and graduated in 1937 with a bachelor's degree in mathematics from Coker College. She earned a master's degree in 1939 from Columbia University in New York City, and became a high school mathematics teacher. As part of the war effort for World War II, she left teaching to work at the Aberdeen Proving Ground; after the war, she became a lecturer at an extension program of the University of Illinois in Galesburg, Illinois.
She began her doctoral studies at Columbia University in 1948, but soon transferred to the University of North Carolina at Chapel Hill, where she completed her doctorate in 1952. Her dissertation, Bounds for Determinants with Dominant Main Diagonal, was supervised by Alfred Brauer.
In 1951, Haynsworth took a faculty position at Wilson College (Pennsylvania). She moved to the National Bureau of Standards in 1955, and returned to academia in 1960 as a faculty member in mathematics at Auburn University. According to Haynsworth, the interview with department chair William Vann Parker at which she was offered the job consisted entirely of working on a research problem in linear algebra with Parker.
At Auburn, Haynsworth eventually became the doctoral advisor to 17 graduate students. She was named a research professor in 1965, and chaired the Southeastern Section of the Mathematical Association of America for 1976–1977. She retired in 1983.
Research
Haynsworth's early research, including her dissertation, concerned the determinants of diagonally dominant matrices, and variants of the Gershgorin circle theorem for bounding the locations of the eigenvalues of matrices. Her later work involved cones of matrices.
It is for two works that she published in 1968 that Haynsworth is particularly known. One of these identified and named the Schur complement, a concept that Haynsworth had already been using in her own work since 1959. In a second paper in 1968 she used this concept to prove what is now known as the Haynsworth inertia additivity formula. This formula provides a decomposition of the triple of numbers of positive, negative, and zero eigenvalues of a matrix into a sum of the triples defined in the same way for a block and its Schur complement in a partitioned Hermitian matrix.

https://en.wikipedia.org/wiki/Eug%C3%A9nie%20Hunsicker | Eugénie Lee Hunsicker is an American mathematician who works at Loughborough University in England as a senior lecturer in pure mathematics and as director of equality and diversity for the school of science.
Her research in pure mathematics has concerned topics "at the intersection of analysis, geometry and topology"; she has also worked on more applied topics in data science and image classification.
Education and career
Hunsicker grew up in Iowa City, and was inspired to do mathematics in part by a high school teacher who was married to a mathematics professor at the University of Iowa. She went to Haverford College, where she was mentored by mathematician Curtis Greene, including two summers of mathematical research with Greene. She also visited the University of Oxford as an exchange student, and earned an honorable mention for the 1992 Alice T. Schafer Prize for excellence in mathematics by an undergraduate woman, won that year by Zvezdelina Stankova. Hunsicker graduated from Haverford magna cum laude in 1992, and went on to graduate study at the University of Chicago, supported in part by a fellowship from the American Association of University Women. Her 1999 dissertation, L(2)-Cohomology and L(2)-Harmonic Forms for Complete Noncompact Kähler and Warped Product Metrics, was jointly supervised by Melvin G. Rothenberg and Kevin Corlette.
She went straight from her doctorate to a faculty position at Lawrence University, a liberal arts college focused primarily on undergraduate teaching, but five years later found herself missing the research life, and after earning tenure she went on the academic job market again. She applied to Loughborough "almost on a whim" after a honeymoon visit to England, and moved there in 2006.
Film
In 2018, as Chair of the London Mathematical Society Women in Maths Committee, Hunsicker worked with filmmaker Irina Linke to produce a short film on Faces of Women in Mathematics.
Recognition
Hunsicker won the Trevor Evans Award of the Mathematical Association of America in 2003 for her work with Laura Taalman on the mathematics of modular architecture. In 2018, she won the Suffrage Science Award for Mathematics and Computing "for her achievements in science and for her work encouraging others to aim for leadership roles in the sector". She was selected as a Fellow of the Association for Women in Mathematics in the Class of 2021 "for leadership of the United Kingdom community of women in mathematics; tireless advocacy for women in mathematics everywhere through talks, writing, and the film 'Faces of Women in Mathematics'; and application of mathematical and statistical expertise to research into equity and diversity issues facing the mathematical community".

https://en.wikipedia.org/wiki/Cyril%20Smith%20%28Marxist%29 | Cyril Smith (1929-2008) was a British lecturer of statistics at the London School of Economics, socialist, and revolutionary humanist.
Political beginnings
Smith began attending Communist Party meetings at University College London in 1947. By his own admission, he was attracted to the "systematic way [of] understand[ing] the world" that Stalinism provided. He quickly became disillusioned, however, during the Lysenko affair, which led to him turning his attention towards the works of Leon Trotsky.
Break with "Leninist Marxism"
Starting in 1987, Smith began to examine what he was beginning to feel was the distortion of Marx's ideas by his own followers. This project first manifested itself in a small booklet titled Communist Society and Marxist Theory. While well aware of its limitations, Smith hoped that the work would begin a dialogue on the subject rather than be the final word. To his dismay, rather than beginning a discussion, the work ended communication entirely with many in his organization. This inspired Smith to probe deeper and work on a more complete account of the matter, a project that Smith would dedicate the remainder of his academic career to in one way or another.
Later in life, Smith would look back on his years as a Trotskyist as necessary for his political trajectory, but years that he put behind himself happily....it [was] important to have seriously participated in the attempt to build the Fourth International and to grasp its ideas; it was also vital to have subsequently and equally seriously ceased to hold to those ideas.
Marx at the Millennium
In 1996, Smith published the results of years of study and examination, the book Marx at the Millennium. Described by Smith as an attempt to discover "what Marx was trying to do," it is as much a critique of how others have attempted to answer that question as it is a presentation of Smith's own answer. Setting his work apart from others of its type, however, is that Smith's critiques were aimed at the views of Marx's followers themselves. For Smith, the degeneration of Marxist thought he believed to have come about was as much, if not more so, the fault of Marxists as it was Marx's right-wing and liberal detractors.Many people these days will tell you ‘Marxism is dead’, usually with the collapse of the USSR in mind. There are still several varieties of ‘Marxist’ who deny it, of course. However, neither side shows much inclination to talk about the actual ideas whose death or survival are being disputed.In his studies, Smith came to the conclusion that there was no basis in the writings of Karl Marx for a "Leninist party" or a "workers' state," putting him sharply at odds with the views of his former comrades and those that he had earlier himself held. In contrast, Smith understood the dictatorship of the proletariat to be the result of "the ability of the proletariat to form itself into a subject." This state, then, was not something apart and above the working-class, direct |

This set is a linear manifold but not necessarily a vector space, since it is not necessarily closed in . If this set is closed (for example, when it is finite-dimensional), it is called the generalized eigenspace of corresponding to the eigenvalue .
Definition of a normal eigenvalue
An eigenvalue of a closed linear operator in the Banach space with domain is called normal (in the original terminology, corresponds to a normally splitting finite-dimensional root subspace), if the following two conditions are satisfied:
The algebraic multiplicity of is finite: , where is the root lineal of corresponding to the eigenvalue ;
The space could be decomposed into a direct sum , where is an invariant subspace of in which has a bounded inverse.
That is, the restriction of onto is an operator with domain and with the range which has a bounded inverse.
Equivalent characterizations of normal eigenvalues
Let be a closed linear densely defined operator in the Banach space . The following statements are equivalent(Theorem III.88):
is a normal eigenvalue;
is an isolated point in and is semi-Fredholm;
is an isolated point in and is Fredholm;
is an isolated point in and is Fredholm of index zero;
is an isolated point in and the rank of the corresponding Riesz projector is finite;
is an isolated point in , its algebraic multiplicity is finite, and the range of is closed.
If is a normal eigenvalue, then the root lineal coincides with the range of the Riesz projector, .
Relation to the discrete spectrum
The above equivalence shows that the set of normal eigenvalues coincides with the discrete spectrum, defined as the set of isolated points of the spectrum with finite rank of the corresponding Riesz projector.
Decomposition of the spectrum of nonselfadjoint operators
The spectrum of a closed operator in the Banach space can be decomposed into the union of two disjoint sets, the set of normal eigenvalues and the fifth type of the essential spectrum:

https://en.wikipedia.org/wiki/Recam%C3%A1n%27s%20sequence | In mathematics and computer science, Recamán's sequence is a well known sequence defined by a recurrence relation. Because its elements are related to the previous elements in a straightforward way, they are often defined using recursion.
It takes its name after its inventor , a Colombian mathematician.
Definition
Recamán's sequence is defined as:
The first terms of the sequence are:
0, 1, 3, 6, 2, 7, 13, 20, 12, 21, 11, 22, 10, 23, 9, 24, 8, 25, 43, 62, 42, 63, 41, 18, 42, 17, 43, 16, 44, 15, 45, 14, 46, 79, 113, 78, 114, 77, 39, 78, 38, 79, 37, 80, 36, 81, 35, 82, 34, 83, 33, 84, 32, 85, 31, 86, 30, 87, 29, 88, 28, 89, 27, 90, 26, 91, 157, 224, 156, 225, 155, ...
On-line encyclopedia of integer sequences (OEIS)
Recamán's sequence was named after its inventor, Colombian mathematician Bernardo Recamán Santos, by Neil Sloane, creator of the On-Line Encyclopedia of Integer Sequences (OEIS). The OEIS entry for this sequence is .
Even when Neil Sloane has collected more than 325,000 sequences since 1964, the Recamán's sequence was referenced in his paper My favorite integer sequences. He also stated that of all the sequences in the OEIS, this one is his favorite to listen to (you can hear it below).
Visual representation
The most-common visualization of the Recamán's sequence is simply plotting its values, such as the figure at right.
On January 14, 2018, the Numberphile YouTube channel published a video titled The Slightly Spooky Recamán Sequence, showing a visualization using alternating semi-circles, as it is shown in the figure at top of this page.
Sound representation
Values of the sequence can be associated with musical notes, in such that case the running of the sequence can be associated with an execution of a musical tune.
Properties
The sequence satisfies:
This is not a permutation of the integers: the first repeated term is . Another one is .
Conjecture
Neil Sloane has conjectured that every number eventually appears, but it has not been proved. Even though 10230 terms have been calculated (in 2018), the number 852,655 has not appeared on the list.
Uses
Besides its mathematical and aesthetic properties, Recamán's sequence can be used to secure 2D images by steganography.
Alternate sequence
The sequence is the most-known sequence invented by Recamán. There is another sequence, less known, defined as:
This OEIS entry is .

https://en.wikipedia.org/wiki/Hettie%20Belle%20Ege | Hettie Belle Ege (March 31, 1861 – November 19, 1942) was an American professor of mathematics. From 1914 to 1916, she was the acting president of Mills College.
Early life
Ege was born in Erie, Illinois on March 31, 1861, the daughter of Joseph Arthur Ege and his second wife, Catherine Rebecca Reisch Ege. Her parents were both from Pennsylvania; her father died the year she was born, and her mother remarried in 1869. She attended Western College in Oxford, Ohio, graduating in 1886; she later graduated from Mills College in 1903, with further studies at the University of Chicago, the University of Munich, and the University of California.
Career
Ege taught school in Ohio and Colorado as a young woman. From 1895 to 1930, she was a professor of mathematics and Dean of Women at Mills College. She also coached the Mills College basketball team. From 1914 to 1916, she was the college's acting president. "Since Mills is to California what Wellesley is to the East," explained a California magazine in 1915, "it is most apparent that the leading spirit of the institution is a dominant figure in the educational activities of the state."
In 1918, she chaperoned a unit of 28 Mills students in the Woman's Land Army, providing ranch labor during wartime shortages. In 1920, the college marked her twenty-five years at Mills with a presentation and convocation. At the festivities marking the school's founder's centennial in 1925, Ege received an honorary doctorate.
After her retirement in 1930, she spent some time in Cambridge, in England. She was a regular guest at Mills College events and alumnae gatherings: in 1933 she was honored as the college's dean emerita, alongside president Aurelia Henry Reinhardt and physician Mariana Bertola, at an annual breakfast of the Mills Club of San Francisco.
Death
Ege died November 19, 1942, aged 81 years, in Oakland, California. Her grave is on the campus of Mills College, and there is a dormitory named for Ege at Mills.

The editors-in-chief are P. W. Duck, P. A. Martin and N. V. Movchan. The journal was established in 1948 to meet a need for a separate English journal that publishes articles focusing on classical mechanics only, in particular, including fluid mechanics and solid mechanics, that were usually published in journals like Proceedings of the Royal Society and Philosophical Transactions of the Royal Society.

https://en.wikipedia.org/wiki/Lee%20Altenberg | Lee Altenberg is an American theoretical biologist. He is on the faculty of the Departments of Information and Computer Sciences and of Mathematics at the University of Hawaiʻi at Mānoa. He is best known for his work that helped establish the evolution of evolvability and modularity in the genotype–phenotype map as areas of investigation in evolutionary biology, for moving theoretical concepts between the fields of evolutionary biology and evolutionary computation, and for his mathematical unification and generalization of modifier gene models for the evolution of biological information transmission, putting under a single mathematical framework the evolution of mutation rates, recombination rates, sexual reproduction rates, and dispersal rates.
Altenberg is an Associate Editor of the journal BioSystems, and serves on the Editorial Boards of the journals Genetic Programming and Evolvable Machines and Artificial Life, and on the IEEE Computational Intelligence Society Task Force on Artificial Life and Complex Adaptive Systems.
Education
Altenberg received his B.A. in genetics in 1980 at the University of California, Berkeley with an honors thesis advised by Glenys Thomson on the theory of frequency-dependent selection. He received his Ph.D. in Biological Sciences in 1985 at Stanford University with advisor Marcus W. Feldman with a dissertation that unified models of modifier gene evolution.
Career
Altenberg held postdoctoral fellowships at Stanford University, North Carolina State University, and Duke University. While a postdoctoral fellow at Duke University, Altenberg offered the first course on evolutionary computation to be given there. When his father became ill with cryoglobulinemia, he moved with him to Hawaii for the warm temperatures. In 2002 Altenberg was appointed associate professor of Information and Computer Sciences at the University of Hawaiʻi at Mānoa. He again offered the first courses in evolutionary computation to be given there. In 2013 Altenberg was a Long-Term Visitor at the Mathematical Biosciences Institute at Ohio State University and in 2014-2016 was a Senior Fellow at the Konrad Lorenz Institute for Evolution and Cognition Research. The University of Hawaiʻi Board of Regents approved his promotion to Full Professor in 2020. Since 2013, Altenberg has been a Research Scholar at the Ronin Institute.
Research
Altenberg's research focuses on uncovering the mathematical relationships within the dynamics of biological evolution, and evolutionary algorithms. He is particularly interested in higher order phenomena such as the evolution of evolvability, the evolution of genetic information transmission, and the evolution of the genotype–phenotype map. His chief accomplishments have been (1) to unify the theory for the evolution of genetic systems (recombination and mutation rates) by embedding them in the space of inclusive inheritance, which includes spatial as well as cultural information, and (2) to develop the concept o |
https://en.wikipedia.org/wiki/Alan%20H.%20Schoenfeld | Alan Henry Schoenfeld (born July 9, 1947) is an American mathematics education researcher and designer. He is the Elizabeth and Edward Conner Professor of Education and Affiliated Professor of Mathematics at the University of California, Berkeley.
Education and career
Schoenfeld was raised in New York City, studying at Queens College (BA 1968) before moving to Stanford University in order to research in pure mathematics (MS 1969, Ph.D 1973 on topology and measure theory). During his graduate studies he became increasingly interested in the teaching and learning of mathematics, particularly of non-routine problem solving. He taught at University of California, Davis (1973–5), University of california, Berkeley (1975–78), Hamilton College (1978–81) and the University of Rochester (1981–1985) before moving back to Berkeley where he now works.
Research
Schoenfeld's work ranges widely across thinking, teaching, and learning in mathematics and beyond, with particular interest in methodological issues aimed at improving the effectiveness of educational research. He has written, edited, or co-edited twenty-two books and more than two hundred articles on thinking and learning. He has focused successively on three major areas:
On problem solving. He made an empirical study of how far mathematics undergraduates tackling non-routine problems can use the strategies set out in George Polya's work How to Solve It The strategies were based on Polya's reflections on how he solved problems. Schoenfeld's study found that the strategies alone are weak, and need to be strengthened by complementary domain-specific tactics. He also showed the importance of students' monitoring their work on a problem and adjusting their tactical and technical moves accordingly. This work was published as Mathematical Problem Solving (1985).
On models of teaching. Understanding the decisions that teachers make in real time in the classroom then became a focus. From the analysis in great detail of videos of mathematics lessons, he and his collaborators developed a model of teaching emphasising three key dimensions – the teacher's knowledge, goals and the beliefs about mathematics. He later generalized the work to real time decision making by professionals, published as the book How we think (2010).
On improving classrooms. Since the 1990s Schoenfeld has become increasingly focused on the challenges of translating research insights into tools and processes that improve teaching and learning in real world classrooms. Working with the design team at the Shell Centre for Mathematical Education. in Nottingham, he has led projects to develop tools for teaching and assessment, culminating in the Mathematics Assessment Project. Complementing this he developed a theoretical framework, Teaching for Robust Understanding (TRU), a model of classrooms in which productive learning is likely to occur. This identifies five key dimensions: the Mathematics; Cognitive demand; Access; Agency, authorit |
