Abstract: For or , isomorphism classes of irreducible -modules for are parametrized by n-dimensional representations of the Weil group of F. We can induce to a representation of , which has index 2 in . That gives a process of “automorphic induction” which to an irreducible -module τ for associates an irreducible -module for . In the present paper we show that if τ is unitary and generic then π is determined by τ, up to isomorphism, via a character identity entirely analogous to the character identity occurring in the automorphic induction process for p-adic fields. This completes the theory of automorphic induction for local and global representations of over number fields. [Copyright &y& Elsevier]
