Auslander-Reiten Components For Lie Algebras Of Reductive Groups

Abstract

this paper we shall study nonperiodic connected components of the stable AuslanderReiten quiver of a reduced enveloping algebra u(L; Ø) associated to a restricted Lie algebra (L; [p]). According to earlier results (cf. [13, 15]) the tree classes of these AR-components are either Euclidean diagrams, or the infinite Dynkin diagrams A1 , D1 ,
