A simple character formula
Résumé
In this paper we prove a character formula expressing the classes of simple representations in the principal block of a simply-connected semisimple algebraic group in terms of baby Verma modules, under the assumption that the characteristic of the base field is bigger than 2h-1, where h is the Coxeter number of h. This provides a replacement for Lusztig's conjecture, valid under a reasonable assumption on the characteristic.
