ASSEM, Ibrahim; CAPPA, Juan Ángel; PLATZECK, María Inés e TREPODE, Sonia. The left part and the Auslander-Reiten components of an artin algebra. Rev. Unión Mat. Argent. [online]. 2005, vol.46, n.2, pp.19-33. ISSN 0041-6932.
The left part of the module category of an artin algebra
consists of all indecomposables whose predecessors have projective dimension at most one. In this paper, we study the Auslander-Reiten components of
(and of its left support
) which intersect
and also the class
of the indecomposable Ext-injectives in the addditive subcategory add
generated by
.
Palavras-chave : artin algebras; Auslander-Reiten quivers; sections; left and right supported algebras.
