Finite Gorenstein representation type implies simple singularity

LW Christensen, G Piepmeyer, J Striuli… - Advances in …, 2008 - Elsevier
Let R be a commutative noetherian local ring and consider the set of isomorphism classes of
indecomposable totally reflexive R-modules. We prove that if this set is finite, then either it …

ω-Gorenstein modules

J Wei - Communications in Algebra®, 2008 - Taylor & Francis
We introduce the notion of ω-Gorenstein modules, where ω is a faithfully balanced self-
orthogonal module. This gives a common generalization of both Gorenstein projective …

Gorenstein injective resolutions, Cousin complexes and top local cohomology modules

K Khashyarmanesh - Algebra Colloquium, 2009 - World Scientific
Let R be a Gorenstein local ring. We show that for a balanced big Cohen–Macaulay module
M over R, the Cousin complex provides a Gorenstein injective resolution of M. Also, over a d …

Gorenstein injective complexes of modules over Noetherian rings

L Zhongkui, Z Chunxia - Journal of Algebra, 2009 - Elsevier
A complex C is called Gorenstein injective if there exists an exact sequence of
complexes⋯→ I− 1→ I0→ I1→⋯ such that each Ii is injective, C= Ker (I0→ I1) and the …

[图书][B] Foundations of commutative rings and their modules

F Wang, H Kim - 2016 - Springer
There are different approaches to characterizing the structures of commutative rings: the
category of modules over commutative rings, homology theories, theories of the star …

The Nakayama functor and its completion for Gorenstein algebras

SB Iyengar, H Krause - arXiv preprint arXiv:2010.05676, 2020 - arxiv.org
Duality properties are studied for a Gorenstein algebra that is finite and projective over its
center. Using the homotopy category of injective modules, it is proved that there is a local …

Sequentially reflexive modules

A Tonolo - Communications in Algebra, 2004 - Taylor & Francis
We generalize the homological characterization of sequentially Cohen–Macaulay modules
over a graded Gorenstein algebra to sequentially reflexive modules over Noetherian, not …

Gorenstein homological properties of tensor rings

XW Chen, M Lu - Nagoya Mathematical Journal, 2020 - cambridge.org
Let $ R $ be a two-sided Noetherian ring, and let $ M $ be a nilpotent $ R $-bimodule, which
is finitely generated on both sides. We study Gorenstein homological properties of the tensor …

Recollements of stable categories of Gorenstein injective modules

Z Wang, T Mu, X Wang - Journal of Algebra and Its Applications, 2021 - World Scientific
Let A and B be rings, U a (B, A)-bimodule and T= A 0 UB be a triangular matrix ring. We first
give an explicit description for Gorenstein injective T-modules over the triangular matrix ring …

Special precovers and preenvelopes of complexes

Z Wang, Z Liu - arXiv preprint arXiv:1301.6595, 2013 - arxiv.org
The notion of an $\mathcal {L} $ complex (for a given class of $ R $-modules $\mathcal {L} $)
was introduced by Gillespie: a complex $ C $ is called $\mathcal {L} $ complex if $ C $ is …
