51Pregeometry (model theory) — Pregeometry, and in full combinatorial pregeometry, are essentially synonyms for matroid . They were introduced by G. C. Rota with the intention of providing a less ineffably cacaphonous alternative term. Also, the term combinatorial geometry,… …
52Polytree — A simple polytree In graph theory, a polytree is a directed graph with at most one undirected path between any two vertices. In other words, a polytree is a directed acyclic graph (DAG) for which there are no undirected cycles either.… …
53Kazhdan–Lusztig polynomial — In representation theory, a Kazhdan–Lusztig polynomial P y,w ( q ) is a member of a family of integral polynomials introduced in work of David Kazhdan and George Lusztig Harv|Kazhdan|Lusztig|1979. They are indexed by pairs of elements y , w of a… …
54Cyclic polytope — In mathematics, a cyclic polytope, denoted C(n,d), is a convex polytope formed as a convex hull of n distinct points on a rational normal curve in Rd, where n is greater than d. These polytopes were studied by Constantin Carathéodory, David Gale …
55Causal set theory bibliography — Main article: Causal Sets This Causal Set Theory Bibliography is intended to aid causal set research. It gathers together academic papers, books, talks and PhD theses related to causal set theory and is intended to help readers find references… …
56Lemme de Sperner —  Ne pas confondre avec le théorème de Sperner sur les familles d ensembles. En mathématiques, le lemme de Sperner, dû à Emanuel Sperner[1], est un analogue combinatoire du théorème du point fixe de Brouwer. Le lemme de Sperner affirme que… …
57Serialism — In music, serialism is a technique for composition that uses sets to describe musical elements, and allows the manipulation of those sets.Fact|date=May 2008 Serialism is often, though not universally, held to begin with twelve tone technique,… …
58Lists of mathematics topics — This article itemizes the various lists of mathematics topics. Some of these lists link to hundreds of articles; some link only to a few. The extremely long list of mathematics articles contains all mathematical articles in alphabetical order.… …
59Areas of mathematics — Mathematics has become a vastly diverse subject over history, and there is a corresponding need to categorize the different areas of mathematics. A number of different classification schemes have arisen, and though they share some similarities,… …
60Bass–Serre theory — is a part of the mathematical subject of group theory that deals with analyzing the algebraic structure of groups acting by automorphisms on simplicial trees. The theory relates group actions on trees with decomposing groups as iterated… …
