Some exceptional extensions of Virasoro vertex operator algebras
Chunrui Ai, Chongying Dong, Xingjun Lin
In this paper, extensions of nonunitary rational Virasoro vertex operator algebras corresponding to some exceptional modular invariants are constructed. The uniqueness of these ext…

Trace functions of the Parafermion vertex operator algebras
Chongying Dong, Victor G. Kac, Li Ren
The trace functions for the Parafermion vertex operator algebra associated to any finite dimensional simple Lie algebra $\g$ and any positive integer are studied and an explici…

Hopf actions on vertex operator algebras
Chongying Dong, Hao Wang
The Hopf actions on vertex operator algebras are investigated. If the action is semisimple, a Schur-Weyl type decomposition is obtained. When the Hopf algebra is finite dimensional…
