Pure-injectivity in the category of Gorenstein projective modules

P Yu, Z Huang - Journal of Algebra and Its Applications, 2017 - World Scientific
In this paper, we introduce and study (weak) pure-injective Gorenstein projective modules.
Let R be an Artin algebra. We prove that the category of weak pure-injective Gorenstein …

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 …

Relative Gorenstein objects in abelian categories

V Becerril, O Mendoza, V Santiago - Communications in Algebra, 2020 - Taylor & Francis
Let A be an abelian category. For a pair (X, Y) of classes of objects in A, we define the weak
and the (X, Y)-Gorenstein relative projective objects in A. We point out that such objects …

Relative Gorenstein rings and duality pairs

J Wang, Z Di - Journal of Algebra and Its Applications, 2020 - World Scientific
Let R be a ring (not necessarily commutative) and (ℒ, 𝒜) a bi-complete duality pair. We
investigate the notions of (flat-typed)(ℒ, 𝒜)-Gorenstein rings, which unify Iwanaga …

Foxby duality and Gorenstein injective and projective modules

E Enochs, O Jenda, J Xu - Transactions of the American Mathematical …, 1996 - ams.org
In 1966, Auslander introduced the notion of the $ G $-dimension of a finitely generated
module over a Cohen-Macaulay noetherian ring and found the basic properties of these …

The class of Gorenstein injective modules is covering if and only if it is closed under direct limits

A Iacob - arXiv preprint arXiv:2403.02493, 2024 - arxiv.org
We prove that the class of Gorenstein injective modules is covering if and only if it is closed
under direct limits. This adds to the list of examples that support Enochs conjecture: Every …

[PDF][PDF] Cartan–Eilenberg Gorenstein projective complexes

G Yang, L Liang - Journal of Algebra and Its Applications, 2014 - researchgate.net
In [13], Verdier introduced the notion of a Cartan–Eilenberg (CE) injective complex. Of
course, there is an obvious dual notion, that of a CE projective complex. In his paper, Verdier …

A note on Gorenstein AC-projective and Gorenstein AC-flat modules

J Wang - Colloquium Mathematicum, 2022 - impan.pl
We establish some relationships between Gorenstein AC-projective modules and
Gorenstein AC-flat modules. As applications, we obtain some new characterizations of …
