(Strongly) Gorenstein injective modules over upper triangular matrix Artin algebras

C Wang, X Yang - Czechoslovak Mathematical Journal, 2017 - Springer
Abstract Let Λ=\left () Λ=(AM 0 B) be an Artin algebra. In view of the characterization of
finitely generated Gorenstein injective Λ-modules under the condition that M is a …

R Hafezi - arXiv preprint arXiv:2109.00467, 2021 - arxiv.org
Let $\text {Gprj}\mbox {-}\Lambda $ denote the category of Gorenstein projective modules

A smashing subcategory of the homotopy category of Gorenstein projective modules

N Gao - Applied Categorical Structures, 2015 - Springer
Let A be an artin algebra of finite CM-type. In this paper, we show that if A is virtually
Gorenstein, then the homotopy category of Gorenstein projective A- modules, denote K(A …

Thick subcategories and virtually Gorenstein algebras

A Beligiannis, H Krause - Illinois Journal of Mathematics, 2008 - projecteuclid.org
An Artin algebra is by definition virtually Gorenstein if the class of modules which are right
orthogonal (with respect to $\operatorname {Ext}^*(-,-) $) to all Gorenstein projective …

Wide subcategories of finitely generated -modules

EN Marcos, O Mendoza, C Sáenz… - Journal of Algebra and …, 2018 - World Scientific
We explore some properties of wide subcategories of the category mod (Λ) of finitely
generated left Λ-modules, for some artin algebra Λ. In particular we look at wide finitely …

Functorial finite subcategories over triangular matrix rings

SO Smalø - Proceedings of the American Mathematical Society, 1991 - ams.org
Let $\Lambda $ and $\Gamma $ be Artin algebras, $ M $ a $\Gamma-\Lambda $-bimodule,
and $ R $ the triangular matrix ring of $\Lambda,\Gamma $, and $ M $; assume that $ R $ is …

Pure-injectivity in the category of Gorenstein projective modules

P Yu, Z Huang - Journal of Algebra and Its Applications, 2017 - World Scientific
In this paper, we introduce and study (weak) pure-injective Gorenstein projective modules.
Let R be an Artin algebra. We prove that the category of weak pure-injective Gorenstein …

Artin algebras of finite type and finite categories of Δ-good modules

DD da Silva - Communications in Algebra, 2016 - Taylor & Francis
We give an alternative proof to the fact that, if the square of the infinite radical of the module
category of an Artin algebra is equal to zero, then the algebra is of finite type by making use …

The singularity category of a quadratic monomial algebra

XW Chen - The Quarterly Journal of Mathematics, 2018 - academic.oup.com
We exploit singular equivalences between artin algebras that are induced from certain
functors between the stable module categories. Such functors are called pre-triangle …
