Symplectic reflection algebras and affine Lie algebras

Pavel Etingof

Department of Mathematics, Massachusetts Institute of Technology

Abstract: The goal of this paper is to present some results and (more importantly) state a number of conjectures suggesting that the representation theory of symplectic reflection algebras for wreath products categorifies certain structures in the representation theory of affine Lie algebras (namely, decompositions of the restriction of the basic representation to finite dimensional and affine subalgebras). These conjectures arose from the insight due to R. Bezrukavnikov and A. Okounkov on the link between quantum connections for Hilbert schemes of resolutions of Kleinian singularities and representations of symplectic reflection algebras.

Key words and phrases: symplectic reflection algebra, affine Lie algebra, basic representation, root, weight.
