The classification of the irreducible admissible C-representations of the reductive p-adic groups G = G(F) (where F is a finite extension of Qp or of Fp((X)) and C an algebraically closed field of character- istic p) is reduced to the classification of the supercuspidal, or equivalently supersingular, C-representations via parabolic induction (Abe-Henniart-Herzig-Vigneras).
