Resumen:
The study of irreducible morphisms and their composites can give importantinformations on the module category of a given algebra, see [5, 6, 9]. Let X andY be indecomposable modules over an algebra. Then, we say that a morphismf : X ! Y is irreducible provided it does not split and whenever f = gh, theneither h is a split monomorphism or g is a split epimorphism. If
