Fusion bases for affine Lie algebras
Abstract
Fusion coefficients for affine Lie algebras are fixed by the corresponding tensorproduct coefficients and a set of threshold levels. It is shown how the information concerning the threshold level is coded in the fusion basis, which is a set of inequalities that completely describes the fusion coefficients. The construction of the su(2) fusion basis is presented in detail.
