The radical of a module category of string algebra

We study how to read from the ordinary quiver of a representation-finite string algebra, the minimal lower bound m ≥ 1 such that the mth power of the radical of its module category vanishes. We also show how to read the degree of any irreducible morphism in such a representation-finite string algebras considering strings.Fil: Chaio, Claudia Alicia. Universidad Nacional de Mar del Plata.
