Gorenstein flat covers of modules over Gorenstein rings

E Enochs, J Xu - Journal of Algebra, 1996 - Elsevier
A left and right Noetherian ringRis called Gorenstein if bothRRandRRhave finite injective
dimensions. These rings were studied by Bass for the commutative case and Iwanaga for …

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 …

Testing for the Gorenstein property

O Celikbas, S Sather-Wagstaff - Collectanea mathematica, 2016 - Springer
We answer a question of Celikbas, Dao, and Takahashi by establishing the following
characterization of Gorenstein rings: a commutative noetherian local ring (R,\mathfrak m)(R …

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 …

On Gorenstein fiber products and applications

S Nasseh, R Takahashi, K VandeBogert - arXiv preprint arXiv:1701.08689, 2017 - arxiv.org
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
finite module of finite Gorenstein injective dimension and maximal Krull dimension then R is …

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 …

[PDF][PDF] On Gorenstein modules over a complete Cohen-Macaulay local ring

RY Sharp - The Quarterly Journal of Mathematics, 1971 - Citeseer
The Cousin complex, C (M), for an A-module M was discussed in (7). In (8), the concept of
Gorenstein module was introduced: a non-zero, finitely generated A-module M is said to be …
