Fusion Rings Related to Affine Weyl Groups
P. Furlan, V. B. Petkova
Abstract
The construction of the fusion ring of a quasi-rational CFT based on sl(3)k at generic level k ∈ Q is reviewed. It is a commutative ring generated by formal characters, elements in the group ring Z[W] of the extended affine Weyl group W of sl(3)k. Some partial results towards the sl(4)k generalisation of this character ring are presented.
