Idempotence — IPAEng|ˌaɪdɨmˈpoʊtəns describes the property of operations in mathematics and computer science which means that multiple applications of the operation does not change the result. The concept of idempotence arises in a number of places in abstract … Wikipedia
Von Neumann regular ring — In mathematics, a ring R is von Neumann regular if for every a in R there exists an x in R with : a = axa .One may think of x as a weak inverse of a ; note however that in general x is not uniquely determined by a .(The regular local rings of… … Wikipedia
Inverse semigroup — In mathematics, an inverse semigroup S is a semigroup in which every element x in S has a unique inverse y in S in the sense that x = xyx and y = yxy. Inverse semigroups appear in a range of contexts; for example, they can be employed in the… … Wikipedia
Loi De Composition Interne — L’algèbre est la branche des mathématiques qui s’intéresse aux ensembles et aux relations qui peuvent y être établies. Elle recherche les conséquences générales qui découlent des propriétés de ces relations, indépendamment de la nature précise… … Wikipédia en Français
Loi de composition interne — Une loi de composition interne (ou, parfois, opération[1]) est un procédé qui, à deux éléments d un ensemble E, associe un troisième élément de E. L addition et la multiplication sont des exemples classiques de lois de composition interne des… … Wikipédia en Français
Projection (mathematics) — Commutativity of this diagram is the universality of projection π, for any map f and set X. Generally speaking, in mathematics, a projection is a mapping of a set (or of a mathematical structure) which is idempotent, which means that a projection … Wikipedia
Glossary of ring theory — Ring theory is the branch of mathematics in which rings are studied: that is, structures supporting both an addition and a multiplication operation. This is a glossary of some terms of the subject. Contents 1 Definition of a ring 2 Types of… … Wikipedia
Modular representation theory — is a branch of mathematics, and that part of representation theory that studies linear representations of finite group G over a field K of positive characteristic. As well as having applications to group theory, modular representations arise… … Wikipedia
Optimistic replication — Optimistic replication[1] (also known as lazy replication[2][3]) is a strategy for replication in which replicas are allowed to diverge. Traditional pessimistic replication systems try to guarantee from the beginning that all of the replicas are… … Wikipedia
Morphism — In mathematics, a morphism is an abstraction derived from structure preserving mappings between two mathematical structures. The notion of morphism recurs in much of contemporary mathematics. In set theory, morphisms are functions; in linear… … Wikipedia
