Character determines the representation?
Sorry, my mistake; what is more difficult is that the character is given by a locally summable function (not that the character determines the representation). Thanks for the reference and clarification. |

Character determines the representation?
The theorem is proved in the book by Harish-Chandra and van Dijk, but only for linear groups. I'm not an expert in the p-adic case, but my vague recollection is there is a nontrivial technical issue towards the end that requires linearity. The proof in Jacquet Langlands is only for GL(2), at least as stated. Maybe an expert can enlighten us. |
