On a deformation theory of finite dimensional modules over repetitive algebras
Adriana Fonce-Camacho, Hernán Giraldo, Pedro Rizzo +1
Let be a basic finite dimensional algebra over an algebraically closed field , and let be the repetitive algebra of . In this article, we prove that…
Relations Between the Strong Global Dimension, Complexes of Fized Size and Derived Category
Y. Calderón-Henao, F. Gallego-Olaya, H. Giraldo
Let be the integer numbers, an algebraically closed field, a finite dimensional -algebra, mod the category of finitely generated right…
Periodic String Complexes over String Algebras
Andrés Franco, Hernán Giraldo, Pedro Rizzo
In this paper we develop combinatorial techniques for the case of string algebras with the aim to give a characterization of string complexes with infinite minimal projective resol…
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…
