Fusion and singular vectors in A1{(1)} highest weight cyclic modules
arXiv:hep-th/9201079 · doi:10.1007/BF02097060
Abstract
We show how the interplay between the fusion formalism of conformal field theory and the Knizhnik--Zamolodchikov equation leads to explicit formulae for the singular vectors in the highest weight representations of A1{(1)}.
