On Gorenstein homological dimension of groups

Y Luo, W Ren - arXiv preprint arXiv:2205.15542, 2022 - arxiv.org
Let $ G $ be a group and $ R $ be a ring. We define the Gorenstein homological dimension
of $ G $ over $ R $, denoted by ${\rm Ghd} _ {R} G $, as the Gorenstein flat dimension of …

For any group $ G $, the Gorenstein homological dimension ${\rm Ghd} _RG $ is defined to
be the Gorenstein flat dimension of the coefficient ring $ R $, which is considered as an …

Gorenstein modules and dimension over large families of infinite groups

DD Stergiopoulou - arXiv preprint arXiv:2307.01161, 2023 - arxiv.org
Projectively coresolved Gorenstein flat modules were introduced by Saroch and Stovicek

Projectively coresolved Gorenstein flat dimension of groups

DD Stergiopoulou - Journal of Algebra, 2024 - Elsevier
In this paper, we introduce and study the projectively coresolved Gorenstein flat dimension
of a group G over a commutative ring R and we prove that this dimension enjoys all the …

In this paper, we study finiteness criteria for the Gorenstein homological dimension of groups
over a commutative ring of finite weak Gorenstein global dimension and provide good …

On the Gorenstein and cohomological dimension of groups

O Talelli - Proceedings of the American Mathematical Society, 2014 - ams.org
Here we relate the Gorenstein dimension of a group $ G $, $\mathrm {Gcd} _ {R} G $, over
$\mathbb Z $ and $\mathbb Q $ to the cohomological dimension of $ G $, $\mathrm {cd} …

Homological dimensions of skew group rings

Y Xiang - Algebra Colloquium, 2020 - World Scientific
Let R be a ring and let H be a subgroup of a finite group G. We consider the weak global
dimension, cotorsion dimension and weak Gorenstein global dimension of the skew group …

Gorenstein global dimensions and cotorsion dimension of rings

D Bennis, N Mahdou - Communications in Algebra, 2009 - Taylor & Francis
In this article, we establish, as a generalization of a result on the classical homological
dimensions of commutative rings, an upper bound on the Gorenstein global dimension of …
