Jacquet-Langlands correspondence and unitarizability. (Jacquet-Langlands et unitarisabilité.) (French) Zbl 1159.22005
The author proves some particular cases of the global Jacquet-Langlands correspondence and deduces that certain representations of an inner form of $$GL_n$$ over a $$p$$-adic field are unitarizable. These results are based on studying a local Jacquet-Langlands correspondence for all smooth irreducible representations. This correspondence is characterized by the fact that it respects the classical Jacquet-Langlands correspondence and commutes with the parabolic induction functor.
