Gorenstein projective dimensions of complexes
ZK Liu, CX Zhang - Acta Mathematica Sinica, English Series, 2011 - Springer
We show that over a right coherent left perfect ring R, a complex C of left R-modules is
Gorenstein projective if and only if C m is Gorenstein projective in R-Mod for all m∈ ℤ …

On invariants and endomorphism rings of certain local cohomology modules
W Mahmood, P Schenzel - Journal of Algebra, 2012 - Elsevier
Let (R, m) denote an n-dimensional Gorenstein ring. For an ideal I⊂ R with gradeI= c we
define new numerical invariants τi, j (I) as the socle dimensions of Hmi (HIn− j (R)). In case of …

We show that a non-trivial fiber product $ S\times_k T $ of commutative noetherian local
rings $ S, T $ with a common residue field $ k $ is Gorenstein if and only if it is a …

A generalization of a theorem of Bass
S Yassemi - Communications in Algebra, 2006 - Taylor & Francis
Let (R, 𝔪) be a commutative Noetherian local ring. In this paper we prove that if R admits a

Cofiniteness of local cohomology modules over regular local rings
G Chiriacescu - Bulletin of the London Mathematical Society, 2000 - cambridge.org
It is well known that for a Noetherian ring R, an ideal I of R, and M a finitely generated R-
module, the local cohomology modules HiI (M) are not always finitely generated. On the …
