Adjoint functors and representation dimensions

CC Xi - Acta Mathematica Sinica, 2006 - Springer
We study the global dimensions of the coherent functors over two categories that are linked
by a pair of adjoint functors. This idea is then exploited to compare the representation …

Representation dimension and quasi-hereditary algebras

C Xi - Advances in Mathematics, 2002 - Elsevier
We study Auslander's representation dimension of Artin algebras, which is by definition the
minimal projective dimension of coherent functors on modules which are both generators …

The derived and extension dimensions of abelian categories

J Zheng, Z Huang - Journal of Algebra, 2022 - Elsevier
For an abelian category A, we establish the relation between its derived and extension
dimensions. Then for an artin algebra Λ, we give the upper bounds of the extension …

[PDF][PDF] On the representation dimension of finite dimensional algebras

C Xi - Journal of Algebra, 2000 - math.uni-bielefeld.de
The importance of the representation finite Artin algebras for the whole representation theory
of Artin algebras is well understood and there is much literature on the subject (see [1, 6 …

On the representation dimension of some classes of algebras

FU Coelho, MI Platzeck - Journal of Algebra, 2004 - Elsevier
We show that the representation dimension of the following classes of algebras is at most
3:(a) Artin algebras A such that the functor HomA (D (A),−) has finite length (or dually, HomA …

[PDF][PDF] Representation dimension of artin algebras

SO Oppermann - Sao Paulo Journal of Mathematical Sciences, 2010 - revistas.usp.br
Auslander has shown that an algebra is of finite representation type, that is, it admits only
finitely many indecomposable modules up to isomorphism, if and only if its representation …

Rejective subcategories of artin algebras and orders

O Iyama - arXiv preprint math/0311281, 2003 - arxiv.org
We will study the resolution dimension of functorially finite subcategories. The subcategories
with the resolution dimension zero correspond to ring epimorphisms, and rejective …

Extension dimensions of derived and stable equivalent algebras

J Zhang, J Zheng - Journal of Algebra, 2024 - Elsevier
The extension dimensions of an Artin algebra give a reasonable way of measuring how far
an algebra is from being representation-finite. In this paper we mainly study the behavior of …
