UNE CONJECTURE DE LUSZTIG POUR LES GROUPES CLASSIQUES

摘要

For a classical group denned over a finite field of sufficiently large characteristic, we prove a conjecture of Lusztig connecting characters of irreducible representations with characteristic functions of character-sheaves. Those functions are precisely normalized in the proof. Our result generalizes Shoji's results to all classical groups. We consider in particular the even orthogonal group, that is neither connected nor with connected center.
