The inductive step of the second Brauer-Thrall conjecture

SO Smalø - Canadian Journal of Mathematics, 1980 - cambridge.org
In this paper we are going to use a result of H. Harada and Y. Sai concerning composition of
nonisomorphisms between indecomposable modules and the theory of almost split …

A functorial approach to monomorphism categories II: Indecomposables

N Gao, J Külshammer, S Kvamme… - Proceedings of the …, 2024 - Wiley Online Library
We investigate the (separated) monomorphism category mono (Q, Λ) $\operatorname
{mono}(Q,\Lambda) $ of a quiver over an Artin algebra Λ $\Lambda $. We show that there …

Dynamical combinatorics and torsion classes

E Barnard, G Todorov, S Zhu - Journal of Pure and Applied Algebra, 2021 - Elsevier
For finite semidistributive lattices the map κ gives a bijection between the sets of completely
join-irreducible elements and completely meet-irreducible elements. Here we study the κ …

[引用][C] The construction of almost split sequences, I

MCR Butler - Proceedings of the London Mathematical Society, 1980 - Wiley Online Library
Almost split sequences of modules were introduced and studied in the last three papers in
the series [1,..., 6] by Auslander and Reiten and, with the related simple functors and …

The numbers of support-tilting modules for a Dynkin algebra

MAA Obaid, SK Nauman, WM Fakieh… - arXiv preprint arXiv …, 2014 - arxiv.org
The Dynkin algebras are the hereditary artin algebras of finite representation type. The
paper exhibits the number of support-tilting modules for any Dynkin algebra. Since the …

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 …

[引用][C] On the number of almost split sequences with indecomposable middle term

H Krause - Bulletin of the London Mathematical Society, 1994 - Wiley Online Library

Relations for Grothendieck groups of Artin algebras

M Auslander - Proceedings of the American Mathematical Society, 1984 - ams.org
MCR Butler has shown that if $\Lambda $ is an artin algebra of finite representation type,
then the almost split sequences generate the relations for the Grothendieck group of …
