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 …

FP-injective dimensions and Gorenstein homology

G Yang, J Wang - Proceedings of the Edinburgh Mathematical …, 2022 - cambridge.org
Let $ R $ be a left coherent ring. It is proven that if an $ R $-module $ M $ has a finite FP-
injective dimension, then the Gorenstein projective (resp. Gorenstein flat) dimension and the …

Strongly Gorenstein flat and Gorenstein FP-injective modules

C Yang - Turkish Journal of Mathematics, 2013 - journals.tubitak.gov.tr
In this paper, we first study the properties of strongly Gorenstein flat (resp. Gorenstein FP-
injective) modules which are special Gorenstein projective (resp. Gorenstein injective) …

Gorenstein flat covers and Gorenstein cotorsion modules over integral group rings

E Enochs, S Estrada, B Torrecillas - Algebras and representation theory, 2005 - Springer
Every module over an Iwanaga–Gorenstein ring has a Gorenstein flat cover [13](however,
only a few nontrivial examples are known). Integral group rings over polycyclic-by-finite …

Relative Gorenstein injective covers with respect to a semidualizing module

E Tavasoli, M Salimi - Czechoslovak Mathematical Journal, 2017 - Springer
Let R be a commutative Noetherian ring and let C be a semidualizing R-module. We prove a
result about the covering properties of the class of relative Gorenstein injective modules with …

Relative Gorenstein flat modules and dimension

D Bennis, R El Maaouy, JRG Rozas… - Communications in …, 2022 - Taylor & Francis
In this article, the new concept of relative Gorenstein flat modules is introduced. We give a
