Resumen:
We study here when there are irreducible morphisms h:X¨Y and h :Y ¨Z between indecomposable modules such that the composite hh is a non-zero morphism in 3(X,Z). In particular, we characterize the representation-finite string algebras and the tilted algebras having such irreducible morphisms.h:X¨Y and h :Y ¨Z between indecomposable modules such that the composite hh is a non-zero morphism in 3(X,Z).
