In algebra, a torsion-free module is a module over a ring such that zero is the only element annihilated by a regular element (non zero-divisor) of the...

stably free module is a module which is close to being free. A module M over a ring R is stably free if there exists a free finitely generated module F over...

In mathematics, a module is a generalization of the notion of vector space in which the field of scalars is replaced by a (not necessarily commutative)...

projective modules enlarges the class of free modules (that is, modules with basis vectors) over a ring, keeping some of the main properties of free modules. Various...

algebra, a module homomorphism is a function between modules that preserves the module structures. Explicitly, if M and N are left modules over a ring...

the resulting indecomposable module is R {\displaystyle R} itself, and this is inside the part of M that is a free module. The summands R / ( q i ) {\displaystyle...

that the nth syzygy module of a module M is free or projective. The above property of invariance, up to the sum direct with free modules, implies that n does...

finitely generated free K[x] module is also free. The construction of higher order syzygy modules is generalized as the definition of free resolutions, which...

covariant additive functor F and some module X. The chain complex for X is defined as follows: first find a free module F 1 {\displaystyle F_{1}} and a surjective...

In algebra, a free presentation of a module M over a commutative ring R is an exact sequence of R-modules: ⨁ i ∈ I R   → f   ⨁ j ∈ J R   → g   M → 0....

mathematics, torsion-free may refer to: Torsion-free group, a group whose only element of finite order is the identity Torsion-free module, module over an integral...

every module has a basis. A module that has a basis is called a free module. Free modules play a fundamental role in module theory, as they may be used...

resolutions consisting, respectively of free modules, projective modules or flat modules. Similarly every module has injective resolutions, which are right...

abstract algebra known as module theory, an injective module is a module Q that shares certain desirable properties with the Z-module Q of all rational numbers...

e.g. M itself, this shows that a module is a quotient of a free module, a useful fact.) A generating set of a module is said to be minimal if no proper...
