[引用][C] Modules of finite projective dimension and cocovers

D Happel, L Unger - Mathematische Annalen, 1996 - Springer
Let A be an Artin algebra. We denote by mod A the category of finitely generated left A-
modules. For XE mod A we denote by pdAX the projective dimension of X. For n CN we …

Complements and the generalized Nakayama conjecture

D Happel, L Unger - CMS Conf. Proc, 1998 - books.google.com
There exists a hierachy of homological conjectures for finitely generated modules over an
Artin algebra A. The generalized Nakayama conjecture for example states that each …

The left and the right parts of a module category

I Assem, FU Coelho, S Trepode - Journal of Algebra, 2004 - Elsevier
In this paper, we study, for an artin algebra, the class LA (and RA) which is a full subcategory
of the category modA of finitely generated A-modules, and which consists of all …

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 …

An approach to the finitistic dimension conjecture

F Huard, M Lanzilotta, O Mendoza - Journal of algebra, 2008 - Elsevier
Let R be a finite dimensional k-algebra over an algebraically closed field k and modR be the
category of all finitely generated left R-modules. For a given full subcategory X of modR, we …

[PDF][PDF] Applications of contravariantly finite subcategories

M Auslander, I Reiten - Advances in Mathematics, 1991 - core.ac.uk
Throughout this paper we assume that all modules are finitely generated over an artin
algebra L!. We denote by mod/i the category of all finitely generated/i-modules. The notions …

The finitistic dimension conjecture and relatively projective modules

C Xi, D Xu - Communications in Contemporary Mathematics, 2013 - World Scientific
The famous finitistic dimension conjecture says that every finite-dimensional 𝕂-algebra over
a field 𝕂 should have finite finitistic dimension. This conjecture is equivalent to the following …
