The homological dimensions of simple modules

N Ding, J Chen - Bulletin of the Australian Mathematical Society, 1993 - cambridge.org
We prove that (a) if R is a commutative coherent ring, the weak global dimension of R equals
the supremum of the flat (or (FP–) injective) dimensions of the simple R-modules;(b) if R is …

Homological dimensions of rigid modules

MR Zargar, O Celikbas, M Gheibi, A Sadeghi - 2018 - projecteuclid.org
We obtain various characterizations of commutative Noetherian local rings (R, m) in terms of
homological dimensions of certain finitely generated modules. Our argument has a series of …

Global dimension and left derived functors of Hom

L Mao, N Ding - Science in China Series A: Mathematics, 2007 - Springer
It is well known that the right global dimension of a ring R is usually computed by the right
derived functors of Hom and the left projective resolutions of right R-modules. In this paper …

FGT-injective dimensions of Π-coherent rings and almost excellent extension

Y Xiang - Proceedings-Mathematical Sciences, 2010 - Springer
We study, in this article, the FGT-injective dimensions of Π-coherent rings. If R is right Π-
coherent, and TI (resp. TF) stands for the class of FGT-injective (resp. FGT-flat) R-modules …

V Gubitosi, R Parra - arXiv preprint arXiv:2207.10599, 2022 - arxiv.org
Let $ G $ be a finite group acting on a ring $ R $ and $ H $ a subgroup of $ G $. In this paper
we compare some homological dimensions over the skew group rings $ RG $ and $ RH …
