AbstractThe fusion rules for the (p,q)-minimal model representations of the Virasoro algebra are shown to come from the group $$G = \mathbb{Z}_2^{p + q - 5} $$ in the following manner. There is a partition $$G = P_1 \cup \; \cdot \cdot \cdot \; \cup P_N $$ into disjoint subsets and a bijection between $$\{ P_1 ,\;...,\;P_N \} $$ and the sectors $$\{ S_1 ,\;...,\;S_N \} $$ of the (p,q)-minimal model such that the fusion rules $$S_i * \;S_j = \sum\nolimits_k {D(S_i ,S_j ,S_k )S_k… 
Type A fusion rules from elementary group theory
We show how the fusion rules for an affine Kac-Moody Lie algebra g of type A_{n-1}, n = 2 or 3, for all positive integral level k, can be obtained from elementary group theory. The orbits of the kth
A new perspective on the Frenkel–Zhu fusion rule theorem
Abstract In this paper we prove a formula for fusion coefficients of affine Kac–Moody algebras first conjectured by Walton [M.A. Walton, Tensor products and fusion rules, Canad. J. Phys. 72 (1994)
Fusion Rules for Affine Kac-Moody Algebras
This is an expository introduction to fusion rules for affine Kac-Moody algebras, with major focus on the algorithmic aspects of their computation and the relationship with tensor product
