Fusion rules and the Patera-Sharp generating-function method
L. Begin, C. Cummins, P. Mathieu +1
We review some contributions on fusion rules that were inspired by the work of Sharp, in particular, the generating-function method for tensor-product coefficients that he develope…

Fusion bases for affine Lie algebras
Luc Begin, Chris Cummins, P. Mathieu
Fusion coefficients for affine Lie algebras are fixed by the corresponding tensor-product coefficients and a set of threshold levels. It is shown how the information concerning the…

Generating functions for tensor products
L. Bégin, C. Cummins, P. Mathieu
This is the first of two articles devoted to a comprehensive exposition of the generating-function method for computing fusion rules in affine Lie algebras. The present paper is en…
