Spectra of modules

P Jørgensen - Journal of Algebra, 2001 - Elsevier
This manuscript solves the problem that the so-called “stable category” Mod Λ of an Artin
algebra is in general not triangulated. The method is to mimick topology and hence first form …

A note on the radical of a module category

C Chaio, S Liu - Communications in Algebra, 2013 - Taylor & Francis
We characterize the finiteness of the representation type of an artin algebra in terms of the
behavior of the projective covers and the injective envelopes of the simple modules with …

From subcategories to the entire module categories

R Hafezi - Forum Mathematicum, 2021 - degruyter.com
In this paper we show that how the representation theory of subcategories (of the category of
modules over an Artin algebra) can be connected to the representation theory of all modules …

Characterizing when the category of Gorenstein projective modules is an abelian category

F Kong - Algebras and Representation Theory, 2014 - Springer
We find sufficient and necessary conditions for the category of Gorenstein projective
modules of an artin algebra being an abelian category, and give another proof for the …

Stable t-structures and homotopy category of Gorenstein-projective modules

N Gao - Journal of Algebra, 2010 - Elsevier
We study the homotopy category of unbounded complexes of Gorenstein-projective
modules with bounded relative homologies. We show the existence of a right recollement of …

[HTML][HTML] Classifying exact categories via Wakamatsu tilting

H Enomoto - Journal of Algebra, 2017 - Elsevier
Using the Morita-type embedding, we show that any exact category with enough projectives
has a realization as a (pre) resolving subcategory of a module category. When the exact …

[引用][C] Extensions of homologically finite subcategories

SA Sikko, SO Smalø - Archiv der Mathematik, 1993 - Springer
Introduction. The study of homologically finite subcategories has turned out to be important
in several contexts, especially in the representation theory of artin algebras. In this paper we …

The stable Auslander-Reiten components of certain monomorphism categories

R Hafezi, Y Zhang - Science China Mathematics, 2024 - Springer
Let A be an Artin algebra and let Gprj-Λ denote the class of all the finitely generated
Gorenstein projective Λ-modules. In this paper, we study the components of the stable …

A functorial approach to monomorphism categories II: Indecomposables

N Gao, J Külshammer, S Kvamme… - arXiv preprint arXiv …, 2023 - arxiv.org
We investigate the (separated) monomorphism category $\operatorname
{mono}(Q,\Lambda) $ of a quiver over an Artin algebra $\Lambda $. We show that there …

[HTML][HTML] Finite cycles of indecomposable modules

P Malicki, JA de la Peña, A Skowroński - Journal of Pure and Applied …, 2015 - Elsevier
We solve a long standing open problem concerning the structure of finite cycles in the
category mod A of finitely generated modules over an arbitrary artin algebra A, that is, the …
