Characterizing cohomological dimension: The cohomological dimension of A ∪ B [PDF]

Topology and Its Applications, 1991
The Menger-Urysohn sum formula is proved for cohomological dimension with respect to integers. The proof is based on a characterization of cohomological dimension \(\dim_{\mathbb{Z}}\) given by the author for metrizable spaces. That characterization is the natural transfer of Edward's characterization of \(\dim_{\mathbb{Z}}\) for compact metric spaces.

On the Gorenstein cohomological dimension of group extensions

Journal of Algebra, 2022
The Gorenstein cohomological dimension is defined for any group G and coincides with the virtual cohomological dimension vcdG, whenever the latter is defined and finite.

Cohomological Dimension of Complexes [PDF]

Communications in Algebra, 2004
In the derived category of the category of modules over a commutative Noetherian ring $R$, we define, for an ideal $\fa$ of $R$, two different types of cohomological dimensions of a complex $X$ in a certain subcategory of the derived category, namely $\cd(\fa, X)=\sup\{\cd(\fa, \H_{\ell}(X))-\ell|\ell\in\Bbb Z\}$ and $-\inf{\mathbf R}\G_{\fa}(X ...

A note on bounded-cohomological dimension of discrete groups

Journal of the Mathematical Society of Japan, 2017
Bounded-cohomological dimension of groups is a relative of classical cohomological dimension, defined in terms of bounded cohomology with trivial coefficients instead of ordinary group cohomology.

Cohomological Dimension of Generalized Local Cohomology Modules

Algebra Colloquium, 2008
The study of the cohomological dimension of algebraic varieties has produced some interesting results and problems in local algebra. Let 𝔞 be an ideal of a commutative Noetherian ring R. For finitely generated R-modules M and N, the concept of cohomological dimension cd 𝔞(M, N) of M and N with respect to 𝔞 is introduced.

On the Cohomological Dimension of Soluble Groups

Canadian Mathematical Bulletin, 1981
AbstractIt is known that every torsion-free soluble group G of finite Hirsch number hG is countable, and its homological and cohomological dimensions over the integers and rationals satisfy the inequalitiesWe prove that G must be finitely generated if the equality hG = cdQG holds.
