The dominant dimension of cohomological Mackey functors [PDF]
, 2018 We show that a separable equivalence between symmetric algebras preserves the dominant dimensions of certain endomorphism algebras of modules. We apply this to show that the dominant dimension of the category coMack(B) of cohomological Mackey functors of

Subgroups of relatively hyperbolic groups of Bredon cohomological dimension 2 [PDF]
, 2017 A remarkable result of Gersten states that the class of hyperbolic groups of cohomological dimension 2 is closed under taking finitely presented (or more generally

Calculating the virtual cohomological dimension of the automorphism group of a RAAG [PDF]
, 2020 We describe an algorithm to find the virtual cohomological dimension of the automorphism group of a right‐angled Artin group. The algorithm works in the relative setting; in particular, it also applies to untwisted automorphism groups and basis ...

Cohomological dimension of a group with respect to finite modules [PDF]
, 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 [PDF]
, 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 ...

Factorization theorems for cohomological dimension [PDF]
, 1988 The well-known factorization theorems for covering dimension dim and compact Hausdorff spaces are here established for the cohomological dimension dimZ using a new characterization of dimZ In particular, it is proved that every mapping f: X → Y from a ...

On the dimension of analytic cohomology
Mathematische Zeitschrift, 1982 If X is a q-convex complex manifold then dimcH~(X, Y) = q for any coherent analytic sheaf. This is a result of Andreotti and Grauert [1] using abstract functional analysis methods. In Buchner, Fritzsche, Sakai [5] the special situation X=IP,\Y was investigated, where Y is an "extremely" homogeneous algebraic submanifold of IP~ (These Y's were called ...

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 ...
