Resumen:
The left part LA of the module category of an artin algebra A consists of all indecomposables whose predecessors have projective dimension at most one. In this paper, we study the Auslander-Reiten components of A (and of its left support Aë) which intersect LA and also the class E of the indecomposableExt-injectives in the addditive subcategory addLA generated by LA.LA of the module category of an artin algebra A consists of all indecomposables whose predecessors have projective dimension at most one.
