Standardly stratified lower triangular -algebras with enough idempotents
E. Marcos, O. Mendoza, C. Sáenz +1
In this paper we study the lower triangular matrix -algebra where and are basic $\mathbb…
Relative Gorenstein objects in abelian categories
Victor Becerril, Octavio Mendoza, Valente Santiago
Let be an abelian category. For a pair of classes of objects in we define the weak and the -Goren…
A generalization of the theory of standardly stratified algebras I: Standardly stratified ringoids
O. Mendoza, M. Ortíz, C. Sáenz +1
We extend the classical notion of standardly stratified -algebra (stated for finite dimensional -algebras) to the more general class of rings, possibly without with enou…
Coherent subcategories of finitely generated -modules
E. N. Marcos, O. Mendoza, C. Sáenz +1
We explore some properties of wide subcategories of the category mod of finitely generated left -modules, for some artin algebra In particular we look at wide finite…
