The book has since been reissued in one volume by Asia Publishing House in 1962. The treatise has been a standard re... |
Wikipedia:History of algebra#0 | Much of the history of Algeria has taken place on the fertile coastal plain of North Africa, which is often called the Maghreb. North Africa served as a transit region for people moving towards Europe or the Middle East, thus, the region's inhabitants have been influenced by populations from other areas, including the ... |
Wikipedia:History of the function concept#0 | The mathematical concept of a function dates from the 17th century in connection with the development of calculus; for example, the slope d y / d x {\displaystyle dy/dx} of a graph at a point was regarded as a function of the x-coordinate of the point. Functions were not explicitly considered in antiquity, but some pre... |
Wikipedia:Hitoshi Kumano-Go#0 | Hitoshi Kumano-Go (4 October 1935 – 24 August 1982) was a Japanese mathematician who specialized in partial differential equations. He is especially recognized for his work on pseudo-differential operators and Fourier integral operators. == Life == Hitoshi Kumano-go was born on 4 October 1935 in Arita, Wakayama Prefect... |
Wikipedia:HoDoMS#0 | HoDoMS (Heads of Departments of Mathematical Sciences) is an educational company that acts as a body to represent the heads of United Kingdom higher education departments of mathematical sciences. It aims to discuss and promote the interests of higher education mathematics in the UK and to facilitate dialogue between d... |
Wikipedia:Hobby–Rice theorem#0 | In mathematics, and in particular the necklace splitting problem, the Hobby–Rice theorem is a result that is useful in establishing the existence of certain solutions. It was proved in 1965 by Charles R. Hobby and John R. Rice; a simplified proof was given in 1976 by A. Pinkus. == The theorem == Define a partition of t... |
Wikipedia:Hochster–Roberts theorem#0 | In algebra, the Hochster–Roberts theorem, introduced by Melvin Hochster and Joel L. Roberts in 1974, states that rings of invariants of linearly reductive groups acting on regular rings are Cohen–Macaulay. In other words, if V is a rational representation of a linearly reductive group G over a field k, then there exist... |
Wikipedia:Hodge star operator#0 | In mathematics, the Hodge star operator or Hodge star is a linear map defined on the exterior algebra of a finite-dimensional oriented vector space endowed with a nondegenerate symmetric bilinear form. Applying the operator to an element of the algebra produces the Hodge dual of the element. This map was introduced by ... |
Wikipedia:Hofstadter's butterfly#0 | In condensed matter physics, Hofstadter's butterfly is a graph of the spectral properties of non-interacting two-dimensional electrons in a perpendicular magnetic field in a lattice. The fractal, self-similar nature of the spectrum was discovered in the 1976 Ph.D. work of Douglas Hofstadter and is one of the early exam... |
Wikipedia:Holmgren's uniqueness theorem#0 | In the theory of partial differential equations, Holmgren's uniqueness theorem, or simply Holmgren's theorem, named after the Swedish mathematician Erik Albert Holmgren (1873–1943), is a uniqueness result for linear partial differential equations with real analytic coefficients. == Simple form of Holmgren's theorem == ... |
Wikipedia:Homeomorphism#0 | In algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces). The word homomorphism comes from the Ancient Greek language: ὁμός (homos) meaning "same" and μορφή (morphe) meaning "form" or "shape". However, the word was a... |
