Abstract
The affine Kac-Moody algebras give rise to rational conformal field theories
(RCFTs) called the Wess-Zumino-Witten (WZW) models. An important component
of an RCFT is its fusion ring, whose structure constants are given by the
associated S-matrix. We apply a fixed point property possessed by the WZW
models ("fixed point factorization") to calculate nonnegative integer matrix
representations of the fusion ring, allowing for the calculation of D-brane
charges in string theory.
