On reduced G-perfection and horizontal linkage relative to a semidualizing module

CB Miranda-Neto, TS Souza - arXiv preprint arXiv:2201.00847, 2022 - arxiv.org
In their investigation of horizontal linkage of modules of finite Gorenstein dimension over a
commutative, Noetherian, semiperfect (eg, local) ring, Dibaei and Sadeghi introduced the …

Covers and Envelopes by V-Gorenstein Modules

EE Enochs, OMG Jenda… - Communications in …, 2005 - Taylor & Francis
In this article, we study V-Gorenstein modules relatives to a dualizing module (Enochs et
al.,). These modules constitute a generalization of the well-known Gorenstein modules and …

Gorenstein homological dimension with respect to a semidualizing module and a generalization of a theorem of Bass

M Salimi, E Tavasoli, S Yassemi - Communications in Algebra, 2014 - Taylor & Francis
Let C be a semidualizing module for a commutative ring R. In this paper, we study the
resulting modules of finite GC-projective dimension in Bass class, showing that they admit …

When do Foxby classes coincide with the classes of modules of finite Gorenstein dimensions?

D Bennis, JR Garcia Rozas, L Oyonarte - 2016 - projecteuclid.org
The relation between the Auslander (resp., Bass) class and the class of modules with finite
Gorenstein projective (resp., injective) dimension is well known when these mentioned …

Minimal complexes of cotorsion flat modules

P Thompson - arXiv preprint arXiv:1702.02985, 2017 - arxiv.org
Let R be a commutative noetherian ring. We give criteria for a complex of cotorsion flat R-
modules to be minimal, in the sense that every self homotopy equivalence is an …

[PDF][PDF] f-Projective and f-Injective Modules

G Yuxian - JOURNAL OF MATHEMATICAL RESEARCH AND …, 2008 - academia.edu
Let R be a ring. A right R-module M is called f-projective if Ext1 (M, N)= 0 for any f-injective
right R-module N. We prove that (F-proj, F-inj) is a complete cotorsion theory, where F-proj …

Commutative rings whose cotorsion modules are pure-injective

F Couchot - arXiv preprint arXiv:1506.02924, 2015 - arxiv.org
Let R be a ring (not necessarily commutative). A left R-module is said to be cotorsion if Ext 1
R (G, M)= 0 for any flat R-module G. It is well known that each pure-injective left R-module is …

Homological aspects of the dual Auslander transpose, II

X Tang, Z Huang - 2017 - projecteuclid.org
Let R and S be rings, and let R ω S be a semidualizing bimodule. We prove that there exists
a Morita equivalence between the class of∞-ω-cotorsion-free modules and a subclass of the …

Duality pairs, generalized Gorenstein modules, and Ding injective envelopes

J Gillespie, A Iacob - Comptes …, 2022 - comptes-rendus.academie-sciences …
Let R be a general ring. Duality pairs of R-modules were introduced by Holm-Jørgensen.
Most examples satisfy further properties making them what we call semi-complete duality …

Weakly Ding injective modules and complexes

A Iacob - Communications in Algebra, 2023 - Taylor & Francis
We consider two classes of modules over coherent rings: the Gorenstein FP-injective
modules, and the weakly Ding injective modules. The Gorenstein FP-injective modules are …
