Geometric approach to some non-Archimedean orbital integrals

Mardi 9 octobre 2018 14:15-15:15 - Jingren Chi - Université de Chicago & LMO

Résumé : Orbital integrals on reductive groups over non-Archimedean local fields have a strong combinatorial flavor as opposed to their Archimedean analogues. In this talk, I will explain how to understand these combinatorial objects via certain algebra-geometric objects, namely the affine Springer fibers and their variants.
