On cohomological dimension of group homomorphisms

open access: yes, 2023
The (co)homological dimension of homomorphism $\phi:G\to H$ is the maximal number $k$ such that the induced homomorphism is nonzero for some $H$-module. The following theorems are proven: THEOREM 1.

Generalized cohomological dimension

open access: yesJournal 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
