Singular compactness and definability for -cotorsion and Gorenstein modules
J Šaroch, J Št'ovíček - Selecta Mathematica, 2020 - Springer
We introduce a general version of the singular compactness theorem which makes it
possible to show that being a Σ Σ-cotorsion module is a property of the complete theory of …

Some applications of extriangulated categories
Y Palu - arXiv preprint arXiv:2307.10019, 2023 - arxiv.org
Extriangulated categories axiomatize extension-closed subcategories of triangulated
categories and generalise both exact categories and triangulated categories. This survey …

[HTML][HTML] Models for singularity categories
H Becker - Advances in Mathematics, 2014 - Elsevier
In this article we construct various models for singularity categories of modules over
differential graded rings. The main technique is the connection between abelian model …

[HTML][HTML] Gorenstein complexes and recollements from cotorsion pairs
J Gillespie - Advances in Mathematics, 2016 - Elsevier
We describe a general correspondence between injective (resp. projective) recollements of
triangulated categories and injective (resp. projective) cotorsion pairs. This provides a model …

[HTML][HTML] Finiteness conditions and cotorsion pairs
D Bravo, MA Pérez - Journal of Pure and Applied Algebra, 2017 - Elsevier
We study the interplay between the notions of n-coherent rings and finitely n-presented
modules, and also study the relative homological algebra associated to them. We show that …

On Ding injective, Ding projective and Ding flat modules and complexes
J Gillespie - 2017 - projecteuclid.org
We characterize Ding modules and complexes over Ding-Chen rings. We show that, over a

Derived, coderived, and contraderived categories of locally presentable abelian categories
L Positselski, J Šťovíček - Journal of Pure and Applied Algebra, 2022 - Elsevier
For a locally presentable abelian category B with a projective generator, we construct the
projective derived and contraderived model structures on the category of complexes …

Frobenius pairs in abelian categories: Correspondences with cotorsion pairs, exact model categories, and Auslander–Buchweitz contexts
Abstract We revisit Auslander–Buchweitz approximation theory and find some relations with
cotorsion pairs and model category structures. From the notion of relative generators, we …
