Research Abstract

(1) We have introduced the notion of an asymptotic algebra of chiral differential operators. We then have constructed, via a chiral Hamiltonian reduction, one such algebra over a resolution of the intersection of the Slodowy slice with the nilpotent cone. We compute the space of global sections of this algebra thereby proving a localization theorem for affine W-algebras at the critical level. This is a joint work with T. Kuwabara and F. Malikov.
(2) We introduced a notion of semi-infinite restriction functor, and shows that it is compatible with admissibility of representations of affine Kac-Moody algebras, enabling an inductive study of Kac-Wakimoto admissible representations.
