Abstract
Let be a simple vertex operator algebra and Aut a finite abelian subgroup such that is rational. We study the representations of based on certain assumptions on -modules. We prove a decomposition theorem for irreducible -modules. We also define an induced module from to and show that every irreducible -module is a quotient module of some induced module. In addition, we prove that is rational in this case.
