Titre A new approach to the Local Langlands Correspondence for $GL_n$ over $p$-adic fields
Date13/01/2011
Horaire14:00 à 15:00
RésumeWe give a new local characterization of the Local Langlands Correspondence, using deformation spaces of $p$-divisible groups, and show its existence by a comparison with the cohomology of some Shimura varieties. This reproves results of Harris-Taylor on the compatibility of local and global correspondences, but completely avoids the use of Igusa varieties and instead relies on the classical method of counting points a la Langlands and Kottwitz. Further, we have a new proof of bijectivity of this correspondence, relying on a description of the inertia-invariant nearby cycles in certain situations.
