| Outline of Final Research Achievements |
Using methods of the geometric Langlands correspondence, we studied the geometric realization of the local Langlands correspondence and the mod p reduction of Shimura varieties. In particular, we showed the Kottwitz conjecture for inner forms of GL(3).We also studied the structure of the moduli space of L-parameters that appears in the geometrization of the local Langlands correspondence.
