Vertex operator algebras associated to admissible representations of
Chongying Dong, Haisheng Li, Geoffrey Mason
The admissible modules for are studied from the point of view of vertex operator algebra. If is rational such that for some coprime positive integ…
Twisted representations of vertex operator algebras
Chongying Dong, Haisheng Li, Geoffrey Mason
Let be a vertex operator algebra and an automorphism of finite order. We construct an associative algebra and a pair of functors between the category of -m…
Regularity of rational vertex operator algebras
Chongying Dong, Haisheng Li, Geoffrey Mason
A regular vertex operator algebra is a vertex operator algebra such that any weak module (without grading) is a direct sum of ordinary irreducible modules. In this paper we give se…
Some twisted sectors for the Moonshine Module
Chongying Dong, Haisheng Li, Geoffrey Mason
For the moonshine module whose automorphism is the Monster We show how to give a uniform existence proof for irreducible -twisted modules for element…
Simple currents and extensions of vertex operator algebras
Chongying Dong, Haisheng Li, Geoffrey Mason
We consider how a vertex operator algebra can be extended to an abelian intertwining algebra by a family of weak twisted modules which are {\em simple currents} associated with sem…
