Generalized Symmetries From Fusion Actions

Chongying Dong, Siu-Hung Ng, Li Ren +1

Let $A$ be a condensable algebra in a modular tensor category $C$ . We define an action of the fusion category $C_{A}$ of $A$ -modules in $C$ on the morph…

Coset constructions and Kac-Wakimoto Hypothesis

Chongying Dong, Li Ren, Feng Xu

Categorical coset constructions are investigated and Kac-Wakimoto Hypothesis associated with pseudo unitary modular tensor categories is proved. In particular, the field identifica…

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…

Orbifold theory for vertex algebras and Galois correspondence

Chongying Dong, Li Ren, Chao Yang

Let $V$ be a simple vertex algebra of countable dimension, $G$ be a finite automorphism group of $V$ and $σ$ be a central element of $G$ . Assume that $S$ is a finite set of…

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…
