Homological conjectures in commutative algebra — In mathematics, the homological conjectures have been a focus of research activity in commutative algebra since the early 1960s. They concern a number of interrelated (sometimes surprisingly so) conjectures relating various homological properties … Wikipedia
Dimension (disambiguation) — A dimension is a spatial characteristic of an object; that is, length, width, or height. Dimension may also be: Contents 1 Science: 2 Mathematics: 3 Media: 4 Other … Wikipedia
Global dimension — In ring theory and homological algebra, the global dimension (or global homological dimension; sometimes just called homological dimension) of a ring A denoted gl dim A , is a non negative integer or infinity which is a homological invariant of… … Wikipedia
Cohomological dimension — In abstract algebra, cohomological dimension is an invariant which measures the homological complexity of representations of a group. It has important applications in geometric group theory, topology, and algebraic number theory. Contents 1… … Wikipedia

D-module — In mathematics, a D module is a module over a ring D of differential operators. The major interest of such D modules is as an approach to the theory of linear partial differential equations. Since around 1970, D module theory has been built up,… … Wikipedia
Regular ring — In commutative algebra, a regular ring is a commutative noetherian ring, such that the localization at every maximal ideal is a regular local ring: that is, every such localization has the property that the minimal number of generators of its… … Wikipedia
Free ideal ring — In mathematics, especially in the field of ring theory, a (left) free ideal ring, or fir, is a ring in which all left ideals are free of unique rank. A ring such that all left ideals with at most n generators is free of unique rank is called an n … Wikipedia
