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…
Cokernels of the Cartan Matrix and Stratifying Systems
Eduardo Marcos, Octavio Mendoza, Corina Sáenz
We study the cokernel of the application given by the Cartan Matrix of a finite dimensional -algebra This produces a finitely generated abelian group, the Cartan grou…
Pullback diagrams, syzygy finite classes and Igusa-Todorov algebras
Diego Bravo, Marcelo Lanzilotta, Octavio Mendoza
For an abelian category , we define the category PEx() of pullback diagrams of short exact sequences in , as a subcategory of the functor cat…
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…
