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 …

The QQ‐shaped derived category of a ring

H Holm, P Jørgensen - Journal of the London Mathematical …, 2022 - Wiley Online Library
For any ring AA and a small, pre‐additive, Hom‐finite, and locally bounded category QQ that
has a Serre functor and satisfies the (strong) retraction property, we show that the category …

Cotorsion pairs and model structures on Morita rings

J Cui, S Rong, P Zhang - Journal of Algebra, 2025 - Elsevier
We study cotorsion pairs and abelian model structures on Morita rings Λ=(ANBAMABB)
which are Artin algebras. Given cotorsion pairs (U, X) and (V, Y) in A-Mod and B-Mod …

Some remarks on projective generators and injective cogenerators

L Liang, NQ Ding, G Yang - Acta Mathematica Sinica, English Series, 2014 - Springer
In this paper, we give a relationship between projective generators (resp., injective
cogenerators) in the category of R-modules and the counterparts in the category of …

FP-injective complexes and FP-injective dimension of complexes

Z Wang, Z Liu - Journal of the Australian Mathematical Society, 2011 - cambridge.org
In this paper we extend the notion of FP-injective modules to that of complexes and
characterize such complexes. We show that some characterizations similar to those for …

Gorenstein projective dimensions of complexes

ZK Liu, CX Zhang - Acta Mathematica Sinica, English Series, 2011 - Springer
We show that over a right coherent left perfect ring R, a complex C of left R-modules is
Gorenstein projective if and only if C m is Gorenstein projective in R-Mod for all m∈ ℤ …

[HTML][HTML] Quillen equivalences for stable categories

G Dalezios, S Estrada, H Holm - Journal of Algebra, 2018 - Elsevier
For an abelian category A we investigate when the stable categories GPro _ j (A) and GIn _ j
(A) are triangulated equivalent. To this end, we realize these stable categories as homotopy …

Characterizations of Ding injective complexes

G Yang, S Estrada - Bulletin of the Malaysian Mathematical Sciences …, 2020 - Springer
Let R be a ring and X a chain complex of R-modules. It is proven that if each term X_i X i is
Ding injective in R-Mod for all i ∈ Z i∈ Z, and there exists an integer k such that each Z _iX …

Gorenstein AC-projective complexes

J Gillespie - Journal of Homotopy and Related Structures, 2018 - Springer
Let R be any ring with identity and Ch (R) C h (R) the category of chain complexes of (left) R-
modules. We show that the Gorenstein AC-projective chain complexes of 1 are the cofibrant …
