Research Interests
My main area of research is geometric representation theory (with applications to algebraic geometry, number theory and mathematical physics). Currently I am working on two main subjects: the first (jointly with M.Finkelberg and H.Nakajima) is an attempt to give a mathematically rigorous approach to the study of 3-dimensional N=4 super-symmetric gauge theories and their quantizations and study representations of the resulting non-commutative algebras. The 2nd subject is related to the p-adic version of the recent series of papers by Etingof, Frenkel and Kazhdan. In those paper the authors study eigen-values of certain Hecke operators acting on the space of L2 half-forms on the moduli space of bundles on a curve over real or complex field. In my current work in progress with Kazhdan and Etingof we are trying to develop p-adic analog of that work.
