n-Cotorsion pairs

M Huerta, O Mendoza, MA Pérez - Journal of Pure and Applied Algebra, 2021 - Elsevier
Motivated by some properties satisfied by Gorenstein projective and Gorenstein injective
modules over an Iwanaga-Gorenstein ring, we present the concept of left and right n …

Relative PGF modules and dimensions

RE Maaouy - arXiv preprint arXiv:2408.07232, 2024 - arxiv.org
Inspired in part by recent work of\v {S} aroch and\v {S}\v {t} ov\'{\i}\v {c} ek in the setting of
Gorenstein homological algebra, we extend the notion of Foxby-Golod ${\rm G_C} …

Cotorsion pairs induced by duality pairs

H Holm, P Jørgensen - Journal of Commutative Algebra, 2009 - JSTOR
We introduce the notion of a duality pair and demonstrate how the left half of such a pair is"
often" covering and preenveloping. As an application, we generalize a result by Enochs et …

The cotorsion pair generated by the Gorenstein projective modules and -pure-injective modules

M Cortés-Izurdiaga, J Šaroch - arXiv preprint arXiv:2104.08602, 2021 - arxiv.org
We prove that, if $\textrm {GProj} $ is the class of all Gorenstein projective modules over a
ring $ R $, then $\mathfrak {GP}=(\textrm {GProj},\textrm {GProj}^\perp) $ is a cotorsion pair …

Separated monic correspondence of cotorsion pairs and semi-Gorenstein-projective modules

XH Luo, S Zhu - Journal of Pure and Applied Algebra, 2024 - Elsevier
Given a finite dimensional algebra A over a field k, and a finite acyclic quiver Q, let Λ= A⊗ kk
Q/I, where kQ is the path algebra of Q over k and I is a monomial ideal. This paper is devoted …

Virtually Gorenstein rings and relative homology of complexes

Z Di, L Liang, J Wang - Journal of Pure and Applied Algebra, 2023 - Elsevier
We extend the notion of virtually Gorenstein rings to the setting of arbitrary rings, and prove
that all rings R of finite Gorenstein weak global dimension are virtually Gorenstein such that …

Stability of Gorenstein flat categories with respect to a semidualizing module

Z Di, Z Liu, J Chen - 2015 - projecteuclid.org
We first introduce in the paper the W_F-Gorenstein modules to establish the following Foxby
equivalence: \xymatrix@C=80ptG(F)∩A_C\ar@\lt0.5ex>r^C⊗_R-\amp\,\,\,\,G(W_F)\ar@\lt0 …

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 …

Gorenstein homology and finiteness properties of local (co) homology

H Faridian - arXiv preprint arXiv:2010.03013, 2020 - arxiv.org
This thesis is comprised of three chapters. The first chapter deals with bounded complexes
of Gorenstein projective and Gorenstein injective modules. Deploying methods of relative …

Gorenstein injective precovers, covers, and envelopes

E Enochs, S Estrada, A Iacob - arXiv preprint arXiv:1301.5694, 2013 - arxiv.org
We give a sufficient condition for the class of Gorenstein injective modules be precovering: if
$ R $ is right noetherian and if the class of Gorenstein injective modules, $\mathcal {GI} $, is …
