| Résume | Exotic Deligne-Langlands correspondence (eDL for short) is a geometric variant of the Deligne-Langlands-Lusztig conjecture (Kazhdan-Lusztig theorem) of affine Hecke algebras of classical groups, which replace its Galois side with more uncommon data. As a model of whole representations, eDL provides much wider scope and simpler description than the original. However, subtle information like being discrete series becomes non-obvious in eDL. Even so, one can deduce precise information like character-computation algorithm of discrete series from eDL, in a way enough to determine formal degree constant. After a brief introduction to eDL, I will explain how to see such information. This talk is based on joint works with Dan Ciubotaru. |
