Note sur les polynomes de Kazhdan-Lusztig
S. Morel
Abstract
The goal of this note is to give a geometric interpretation of a theorem of Brenti that calculates Kazhdan-Lusztig polynomials associated to Coxeter groups, if the Coxeter group is isomorphic to a Weyl group. ----- Le but de cette note est de donner une interpretation geometrique d'une formule de Brenti pour les polynomes de Kazhdan-Lusztig associes aux groupes de Coxeter qui sont isomorphes a un groupe de Weyl.
