Abstract:Soit F un corps commutatif localement compact non archimédien, et soit D une algèbrè a division de centre F. Nous prouvons que toute représentation irréductible supercuspidale du groupe GLm(D), de niveau non nul, est l'induite compacte d'une représentation d'un sous-groupe ouvert compact modulo le centre de GLm(D). Plus précisément, nous prouvons que de telles représentations contiennent un type simple maximal au sens de Bushnell et Kutzko.Abstract Let F be a non-Archimedean locally compact field and let D be … Show more
“…In particular, s ρ is an integer dividing the degree of D and coprime to m ([26, Theorem B.2.b] and [9, Lemma 2.4]). Alternatively, Theorem A.1 (and the information about s ρ ) is also proved in [57, §4] (which works in any characteristic as was pointed out in [4]) without the Jacquet-Langlands correspondence but using instead the theory of types developed in [21,22,[52][53][54][55][56] to reduce the problem to a question about the Hecke algebra of type A n .…”

“…However, Bernstein's method is not applicable to the case F = D since it relies crucially on the properties of the mirabolic subgroup.

“…The Zelevinsky classification in the case D = F is due to Mínguez-Sécherre [42] who consider representations over fields of characteristic different from the residual characteristic of F . They use type theory which was developed by Bushnell-Kutzko in the case D = F [22] and subsequently by Sécherre and his co-authors in the general case in a series of papers ( [21,[52][53][54][55][56]). All these methods ultimately reduce the classification to the case D = F .…”
We give new criteria for the irreducibility of parabolic induction on the general linear group and its inner forms over a local non-archimedean field. In particular, we give a necessary and sufficient condition when the inducing data is of the form π ⊗ σ where π is a ladder representation and σ is an arbitrary irreducible representation. As an application we simplify the proof of the classification of the unitary dual.

Abstract. -Let F be a non-Archimedean local field of residual characteristic p, and ℓ be a prime number different from p. We consider the local Jacquet-Langlands correspondence between ℓ-adic discrete series of GLnpFq and an inner form GLmpDq. We show that it respects the relationship of congruence modulo ℓ. More precisely, we show that two integral ℓ-adic discrete series of GLnpFq are congruent modulo ℓ if and only if the same holds for their Jacquet-Langlands transfers to GLmpDq.
“…The irreducible supercuspidal representations of GL n (K) is classified in [BK] via type theory, which describes supercuspidal representations as compact inductions of representations of some open subgroups that are compact modulo center. More generally, type theory for representations of A × is developed in a series of papers [Se1], [Se2], [Se3], [SS1], [BSS] and [SS2]. So it is natural to seek a description of the LJLC via type theory.…”
We give a description of the local Jacquet-Langlands correspondence for simple supercuspidal representations via type theory. As a consequence, we show that the endo-classes for such representations are invariant under the local Jacquet-Langlands correspondence.
