Abstract

We consider two types of quotients of the integrable modules of sl^2\hat{sl}_2. These spaces of coinvariants have dimensions described in terms of the Verlinde algebra of level-kk. We describe monomial bases for the spaces of coinvariants, which leads to a fermionic description of these spaces. For k=1k=1, we give the explicit formulas for the characters. We also present recursion relations satisfied by the characters and the monomial bases.
