Fusion Products of Twisted Modules in Permutation Orbifolds: II

Abstract

Let $V$ be a simple, rational, $C_2$-cofinite vertex operator algebra of CFT type, and let $k$ be a positive integer. In this paper, we determine the fusion products of twisted modules for $V^{\otimes k}$ and $G=⟨g⟩$ generated by any permutation $g\in S_k$.
