Soit un corps local non archimédien de caractéristique résiduelle différente de et . Nous définissons strates semi-simples et caractères semi-simples pour le groupe exceptionnel à l’aide des objets analogues pour le groupe , des automorphismes de trialité et d’une correspondance de Glauberman. Nous construisons alors les types semi-simples associés et nous donnons des conditions suffisantes pour que ces types s’induisent irréductiblement, obtenant ainsi des représentations supercuspidales du groupe .
Let be a local non archimedean field of residual characteristic different from and . We define semisimple strata and semisimple characters for the exceptional group , using the analogous objects for the group , the triality automorphisms and a Glauberman correspondence. We then construct the associated semisimple types and give sufficient conditions for those types to induce irreducibly, thus obtaining supercuspidal representations of the group .
