On a deformation theory of finite dimensional modules over repetitive algebras

Adriana Fonce-Camacho, Hernán Giraldo, Pedro Rizzo +1

Let $Λ$ be a basic finite dimensional algebra over an algebraically closed field $k$ , and let $Λ$ be the repetitive algebra of $Λ$ . In this article, we prove that…

On irreducible morphisms and Auslander-Reiten triangles in the stable category of modules over repetitive algebras

Yohny Calderón-Henao, Hernán Giraldo, José A. Vélez-Marulanda

Let $k$ be an algebraically closed field, let $Λ$ be a finite dimensional $k$ -algebra, and let $Λ$ be the repetitive algebra of $Λ$ . For the stable catego…
