Fusion products of twisted modules in permutation orbifolds

Abstract

Let $V$ be a vertex operator algebra, $k$ a positive integer and $\sigma$ a permutation automorphism of the vertex operator algebra $V^{\otimes k}$. In this paper, we determine the fusion product of any $V^{\otimes k}$-module with any $\sigma$-twisted $V^{\otimes k}$-module.
