Cohomological dimension and top local cohomology modules
Rocky Mountain Journal of Mathematics, 2019 Let \(R\) be a commutative Noetherian ring with identity. Let \(I\) be an ideal of \(R\) and \(M\) a finitely generated \(R\)-module. The authors prove some interesting results concerning the notion of cohomological dimension. The \textit{cohomological dimension} of \(M\) with respect to \(I\) is defined as \[ \text{cd}(I,M):=\sup\{i\in \mathbb{N}_0 ...

A Note on Artinianess of Certain Generalized [PDF]
Journal of Sciences, Islamic Republic of Iran, 2008 Let ?: R0?R be a ring homomorphism and suppose that a and a0, respectively, are ideals of R and R0 such that is an Artinian ring. Let M and N be two finitely generated R-modules and suppose that (R0,m0) is a local ring. In this note we prove that the R-

Cohomological dimension of a group with respect to finite modules
, 1977 The purpose of this paper is to compare the cohomological dimension of a group, relative to finite modules, with the cohomological dimension, in the usual sense, of its profinite completion.

Automorphisms of pro-p groups of finite virtual cohomological dimension
, 2015 Let G be a pro-p group of finite cohomological dimension and type F P-infinity and T be a finite p-group of automorphisms of G. We prove that the group of fixed points of T in G is again a pro-p group of type F P-infinity (in particular it is finitely ...

Generalized cohomological dimension
Journal of Pure and Applied Algebra, 1986 The cohomological dimension cd of a group G is an invariant which is extremely sensitive to the presence of torsion. There are several ways to reduce this sensitivity. An easy alternative is to use \(cd_{{\mathbb{Q}}}G\) instead of \(cd_{{\mathbb{Z}}}G\) or the virtual cohomological dimension vcd G. In the paper under review, a new invariant is defined
