Orbifolds and minimal modular extensions

Chongying Dong, Siu-Hung Ng, Li Ren

Let $V$ be a simple, rational, $C_{2}$ -cofinite vertex operator algebra and $G$ a finite group acting faithfully on $V$ as automorphisms, which is simply called a rational vertex ope…

Super orbifold theory

Chongying Dong, Li Ren, Meiling Yang

Let $V$ be a simple vertex operator superalgebra and $G$ a finite automorphism group of $V$ containing the canonical automorphism $σ$ such that $V^{G}$ is regular. It is proved that…

S-matrix in orbifold theory

Chongying Dong, Li Ren, Feng Xu

The restricted $S$ -matrix of $V^{G}$ is determined for any regular vertex operator algebra $V$ and finite automorphism group $G$ of $V .$ As an application, the $S$ -matrices for cycli…

Vertex operator superalgebras and 16-fold way

Chongying Dong, Siu-Hung Ng, Li Ren

Let $V$ be a vertex operator superalgebra with the natural order 2 automorphism $σ$ . Under suitable conditions on $V$ , the $σ$ -fixed subspace $V_{0 ˉ}$ is a vertex operator alge…

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 $k$ are studied and an explici…

On Orbifold Theory

Chongying Dong, Li Ren, Feng Xu

Let V be a simple vertex operator algebra and G a finite automorphism group of V such that V^G is regular. It is proved that every irreducible V^G-module occurs in an irreducible g…
