String and band complexes over SAG algebras
Andrés Franco, Hernán Giraldo, Pedro Rizzo
We give a combinatorial description of a family of indecomposable objects in the bounded derived categories of a new class of algebras: string almost gentle algebras. These indecom…

Derived tame Nakayama algebras
Viktor Bekkert, Hernan Giraldo, Jose A. Velez-Marulanda
We determine the derived representation type of Nakayama algebras and prove that a derived tame Nakayama algebra without simple projective module is gentle or derived equivalent to…

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