Sur la cohomologie des compactifications de variétés de Deligne-Lusztig (1310.7259v2)
Published 27 Oct 2013 in math.AG and math.RT
Abstract: In this article, we study the \'etale cohomology of the compactification of Deligne-Lusztig varieties associated to a Coxeter element. We prove a result for the integral coefficients in the case of general linear group $GL_d$, and we conjecture that the similar result holds for general reductive groups.
