Coxeter orbits and Brauer trees II

Published 24 Nov 2010 in math.RT and math.GR | (1011.5478v2)

Abstract: The purpose of this paper is to discuss the validity of the assumptions (W) and (S) stated in a previous work, about the torsion in the modular l-adic cohomology of Deligne-Lusztig varieties associated to Coxeter elements. We prove that both (W) and (S) hold except for groups of type E_7 or E_8.
