Resumen:
We study the non-zero composition of n irreducible morphisms between modules in a regular component of the Auslander-Reiten quiver lying in the n + 1-th power of the radical of a module category over an artin algebra. We apply such results to show that the composition of three irreducible morphisms between indecomposable modules cannot lie in radical to the fourth power and not in radical to the 6th power.
