Resumen de Dualité dans l'espace des caractères virtuels tempérés d'un groupe réductif p -adique

Karem Bettaïeb

• We define an involution on the set of tempered virtual characters of a connected reductive p-adic group. This involution commutes with character of parabolic induction and with truncation. It also preserves the irreducible characters up to sign and the elliptic inner product.
