William Fogg Osgood was an American mathematician.
In mathematics, Harish-Chandra's regularity theorem, introduced by Harish-Chandra, states that every invariant eigendistribution on a semisimple Lie group, and in particular every character of an irreducible unitary representation on a Hilbert space, is given by a locally integrable function. Harish-Chandra proved a similar theorem for semisimple p-adic groups.
Adolf Edward Nussbaum was a German-born American theoretical mathematician who was a professor of mathematics at Washington University in St. Louis for nearly 40 years. He worked with others in 20th-century theoretical physics and mathematics such as J. Robert Oppenheimer and John von Neumann, and was acquainted with Albert Einstein.
Patrick Dehornoy was a mathematician at the University of Caen Normandy who worked on set theory and group theory.
In geometric topology, a branch of mathematics, a crumpled cube is any space in R3 homeomorphic to a 2-sphere together with its interior. Lininger showed in 1965 that the union of a crumpled cube and an open 3-ball glued along their boundaries is a 3-sphere.
Stefan Andrus Burr is a mathematician and computer scientist, specializing in graph theory and number theory, particularly Ramsey theory. He is a retired professor of Computer Science at The City College of New York.
In mathematics, a modular invariant of a group is an invariant of a finite group acting on a vector space of positive characteristic. The study of modular invariants was originated in about 1914 by Dickson (2004).
In mathematics, Birkhoff factorization or Birkhoff decomposition, introduced by George David Birkhoff, is the factorization of an invertible matrix with coefficients that are Laurent polynomials in into a product , where has entries that are polynomials in , is diagonal, and has entries that are polynomials in . There are several variations where the general linear group is replaced by some other reductive algebraic group, due to Alexander Grothendieck.
In mathematics, sieved Pollaczek polynomials are a family of sieved orthogonal polynomials, introduced by Ismail (1985). Their recurrence relations are a modified version of the recurrence relations for Pollaczek polynomials.
In algebra, the term Hermite ring has been applied to three different objects.
In mathematics, the Jessen–Wintner theorem, introduced by Jessen and Wintner, asserts that a random variable of Jessen–Wintner type, meaning the sum of an almost surely convergent series of independent discrete random variables, is of pure type.
In mathematics complex analysis, the Sarason interpolation theorem, introduced by Sarason, is a generalization of the Caratheodory interpolation theorem and Nevanlinna–Pick interpolation.
Isidore Isaac Hirschman Jr. (1922–1990) was an American mathematician, and professor at Washington University in St. Louis working on analysis.
In mathematics, Brewer sums are finite character sum introduced by Brewer related to Jacobsthal sums.
Steven Joel Takiff is an American mathematician who introduced what became Takiff algebras in 1971.
In algebra, a Lie-admissible algebra, introduced by A. Adrian Albert, is a algebra that becomes a Lie algebra under the bracket [a, b] = ab − ba. Examples include associative algebras, Lie algebras, and Okubo algebras.
Bertram John Walsh is an American mathematician, specializing in locally convex spaces, harmonic analysis, and partial differential equations.
Thomas Henry Brylawski was an American mathematician and professor at the University of North Carolina, Chapel Hill. He worked primarily in matroid theory.
Albert "Tommy" Wilansky was a Canadian-American mathematician, known for introducing Smith numbers.
Wallace Smith Martindale III is an American mathematician, known for Martindale's Theorem (1969) and the Martindale ring of quotients introduced in the proof of the theorem. His 1969 paper generalizes Posner's theorem and a theorem of Amitsur and gives an independent, unified proof of the two theorems.
