Abstract

We prove that if A is a string algebra then there are not three irreducible morphisms between indecomposable A-modules such that its composition belongs to whenever the compositions of two of them are not in Moreover, for any positive integer we show that there are algebras where their module category have n irreducible morphisms such that their composition is in
