New Level-0 Action of Uq(sl2) on Level-1 Modules
Abstract
A level-0 action of Uq(sl2) is defined on the sum of level-1 irreducible highest weight modules. With the aid of the affine Hecke algebras, this action is realized on the basis created by the vertex operators. This is a q-analogue of the Yangian symmetry in conformal field theory.
