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…

Level- limit linear series
Eduardo Esteves, Antonio Nigro, Pedro Rizzo
We introduce the notion of level- limit linear series, which describe limits of linear series along families of smooth curves degenerating to a singular curve . We treat here…
