The local Langlands correspondence for disconnected reductive groups
The local Langlands correspondence for disconnected reductive groups
Let be a connected, quasi-split reductive group over , let be a rigid inner twist of , and let denote the set of -conjugacy classes of -relevant enhanced L-parameters. Here is the set of irreducible representations of . The local Langlands correspondence. There exists a bijection
and it satisfies a lot of properties. The statement proposes a local Langlands parametrization for irreducible representations of rigid inner forms by relevant enhanced L-parameters; the parser supplies no evidence resolving it, so its status remains open.
