The PBW Filtration, Demazure Modules and Toroidal Current Algebras
Let L be the basic (level one vacuum) representation of the affine Kac-Moody Lie algebra ^g. The m-th space Fm of the PBW filtration on L is a linear span of vectors of the form x1¼xlv0, where l ≤ m, xi Î ^g and v0 is a highest weight vector of L. In this paper we give two descriptions of the associ...
