Contravariantly finite subcategories closed under predecessors

I Assem, FU Coelho, S Trepode - Journal of Algebra, 2009 - Elsevier
Let A be an Artin algebra and modA be the category of finitely generated right A-modules.
We prove that an additive full subcategory C of modA closed under predecessors is …

Trace quotient modules

M Auslander, EL Green - Illinois Journal of Mathematics, 1988 - projecteuclid.org
This paper studies properties of a class of modules over an artin algebra called trace
quotient modules whichwe define below. We were led to consider these modules during our …

Representation theory of artin algebras v: methods for computing aimost split sequences and irreducible morphisms

The relationship between homological properties and representation theoretic realization of Artin algebras

O Iyama - Transactions of the American Mathematical Society, 2005 - ams.org
We will study the relationship of quite different objects in the theory of artin algebras, namely
Auslander-regular rings of global dimension two, torsion theories, $\tau $-categories and …

Higher-dimensional Auslander–Reiten theory on (d+ 2)-angulated categories

P Zhou - Glasgow Mathematical Journal, 2022 - cambridge.org
Let be a-angulated category with d-suspension functor. Our main results show that every
Serre functor on is a-angulated functor. We also show that has a Serre functor if and only if …
