Recollements induced by monomorphism categories

Z Wang, Z Liu - Journal of Algebra, 2022 - Elsevier
Let R be any associative ring, na positive integer and X a full subcategory of the category of
R-modules. The monomorphism category S n (X) of X consists of all the objects (X i, φ i) …

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 …

Auslander conditions and tilting-like cotorsion pairs

J Wang, Y Li, J Wu, J Hu - Journal of Algebra, 2023 - Elsevier
We study homological behavior of modules satisfying the Auslander condition. Assume that
AC is the class of left R-modules satisfying the Auslander condition. It is proved that each …

For a $ k $-algebra $ A $, a quiver $ Q $, and an ideal $ I $ of $ kQ $ generated by monomial
relations, let $\Lambda:= A\otimes_k kQ/I $. We introduce the monic representations of $(Q …

New model structures and projective (injective) cotorsion pairs

A Xu - Journal of Algebra and Its Applications, 2023 - World Scientific
Let 𝒟 be either the category of R-modules or the category of chain complexes of R-modules

The orthogonal complement relative to the functor extension of the class of all Gorenstein projective modules

M Tamekkante - 2010 - projecteuclid.org
In this paper, we study the pair (GP(R),GP(R)^⊥) where GP(R) is the class of all Gorenstein
projective modules. We prove that it is a complete hereditary cotorsion theory, provided …

Generalized Gorenstein modules

A Iacob - Algebra Colloquium, 2022 - World Scientific
We introduce a generalization of the Gorenstein injective modules: the Gorenstein FP n-
injective modules (denoted by GI n). They are the cycles of the exact complexes of injective …

Tilting subcategories with respect to cotorsion triples in abelian categories

Z Di, J Wei, X Zhang, J Chen - Proceedings of the Royal Society of …, 2017 - cambridge.org
Given a non-negative integer n and a complete hereditary cotorsion triple, the notion of
subcategories in an abelian category is introduced. It is proved that a virtually Gorenstein …
