Cuspidal representations of sl(n+1)

Dimitar Grantcharov, Vera Serganova

Published 2007-10-14, updated 2010-01-24Version 2

In this paper we study the subcategory of cuspidal modules of the category of weight modules over the Lie algebra sl(n+1). Our main result is a complete classification and explicit description of the indecomposable cuspidal modules.
