Shapes of Auslander-Reiten Triangles

Edson Ribeiro Alvares, Sônia Maria Fernandes, Hernán Giraldo

Our main theorem classifies the Auslander-Reiten triangles according to properties of the morphisms involved. As a consequence, we are able to compute the mapping cone of an irredu…

On Singular Equivalences of Morita Type and Universal Deformation Rings for Gorenstein Algebras

Viktor Bekkert, Hernan Giraldo, Jose A. Velez-Marulanda

Let $Λ$ be a finite-dimensional algebra over a fixed algebraically closed field $k$ of arbitrary characteristic, and let $V$ be a finitely generated $Λ$ -module. It follows…

Universal deformation rings for a class of self-injective special biserial algebras

Johny Calderon-Henao, Hernan Giraldo, Ricardo Rueda-Robayo +1

Let $k$ be an algebraically closed field of arbitrary characteristic, let $Λ$ be a finite dimensional $k$ -algebra and let $V$ be a $Λ$ -module with stable endomorp…
