Gorenstein homological aspects of monomorphism categories via Morita rings

N Gao, C Psaroudakis - Algebras and Representation Theory, 2017 - Springer
In this paper we construct Gorenstein-projective modules over Morita rings with zero
bimodule homomorphisms and we provide sufficient conditions for such rings to be …

Complete cohomology for extriangulated categories

J Hu, D Zhang, T Zhao, P Zhou - Algebra Colloquium, 2021 - World Scientific
Let (C, E, s) be an extriangulated category with a proper class ξ of E-triangles. We study
complete cohomology of objects in (C, E, s) by applying ξ-projective resolutions and ξ …

On the finiteness of Gorenstein homological dimensions

I Emmanouil - Journal of Algebra, 2012 - Elsevier
In this paper, we study certain properties of modules of finite Gorenstein projective, injective
and flat dimensions. We examine conditions which imply that all Gorenstein projective …

On stability of Gorenstein categories

A Xu, N Ding - Communications in Algebra, 2013 - Taylor & Francis
We show that an iteration of the procedure used to define the Gorenstein projective modules
over a ring R yields exactly the Gorenstein projective modules. Specifically, given an exact …

Frobenius functors and Gorenstein homological properties

XW Chen, W Ren - Journal of Algebra, 2022 - Elsevier
We prove that any faithful Frobenius functor between abelian categories preserves the
Gorenstein projective dimension of objects. Consequently, it preserves and reflects …

[HTML][HTML] Relative singularity categories

H Li, Z Huang - Journal of Pure and Applied Algebra, 2015 - Elsevier
We study the properties of the relative derived category DC b (A) of an abelian category A
relative to a full and additive subcategory C. In particular, when A= A-mod for a finite …

Direct limits of Gorenstein injective modules

A Iacob - arXiv preprint arXiv:2308.08699, 2023 - arxiv.org
One of the open problems in Gorenstein homological algebra is: when is the class of
Gorenstein injective modules closed under arbitrary direct limits? It is known that if the class …

From CM-finite to CM-free

F Kong, P Zhang - arXiv preprint arXiv:1212.6184, 2012 - arxiv.org
The aim of this paper is twofold. On one hand, we prove a slight generalization of the
stability for Gorenstein categories in [SWSW] and [Huang]; and show that the relative …

Enhanced Auslander-Reiten duality and tilting theory for singularity categories

N Hanihara, O Iyama - arXiv preprint arXiv:2209.14090, 2022 - arxiv.org
We establish a general method to construct triangle equivalences between the singularity
categories of (commutative and non-commutative) Gorenstein rings and the cluster …

$\V\W $-Gorenstein categories

G Zhao, J Sun - Turkish Journal of Mathematics, 2016 - journals.tubitak.gov.tr
Let $\A $ be an abelian category, and $\V $, $\W $ two additive full subcategories of $\A $.
We introduce and study the $\V\W $-Gorenstein subcategory of $\A $, which unifies many …
