Spaces of coinvariants and fusion product II. Affine sl_2 character formulas in terms of Kostka polynomials
B. Feigin, M. Jimbo, R. Kedem +2
In this paper, we continue our study of the Hilbert polynomials of coinvariants begun in our previous work math.QA/0205324 (paper I). We describe the sl_n-fusion products for symme…

Spaces of coinvariants and fusion product I. From equivalence theorem to Kostka polynomials
B. Feigin, M. Jimbo, R. Kedem +2
The fusion rule gives the dimensions of spaces of conformal blocks in the WZW theory. We prove a dimension formula similar to the fusion rulefor spaces of coinvariants of affine Li…
