Hopf actions on vertex algebras

Chongying Dong, Li Ren, Chao Yang

In this article, we investigate Hopf actions on vertex algebras. Our first main result is that every finite-dimensional Hopf algebra that inner faithfully acts on a given π_2-injec…

Modular $A_{n} (V)$ theory

Li Ren

A series of associative algebras $A_{n} (V)$ for a vertex operator algebra $V$ over an arbitrary algebraically closed field and nonnegative integers $n$ are constructed such that ther…

Congruence Property in Orbifold Theory

Chongying Dong, Li Ren

Let $V$ be a rational, selfdual, $C_{2}$ -cofinite vertex operator algebra of CFT type, and $G$ a finite automorphism group of $V .$ It is proved that the kernel of the representation…
