Abstract
AbstractWe characterize the Local Langlands Correspondence (LLC) for inner forms of GLn via the Jacquet–Langlands Correspondence (JLC) and compatibility with the Langlands Classification. We show that LLC satisfies a natural compatibility with parabolic induction and characterize LLC for inner forms as a unique family of bijections Π(GLr(D)) → Φ(GLr(D)) for each r, (for a fixed D), satisfying certain properties. We construct a surjective map of Bernstein centers ℨ(GLn(F)) → ℨ(GLr(D)) and show this produces pairs of matching distributions in the sense of Haines. Finally, we construct explicit Iwahori-biinvariant matching functions for unit elements in the parahoric Hecke algebras of GLr(D), and thereby produce many explicit pairs of matching functions.
