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…

Fusion Products of Twisted Modules in Permutation Orbifolds: II

Chongying Dong, Feng Xu, Nina Yu

Let $V$ be a simple, rational, $C_{2}$ -cofinite vertex operator algebra of CFT type, and let $k$ be a positive integer. In this paper, we determine the fusion products of twisted m…

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…

Permutation orbifolds of vertex operator superalgebra and associative algebras

Chongying Dong, Feng Xu, Nina Yu

Let $V$ be a vertex operator superalgebra and $g = (12 \dots k)$ be a $k$ -cycle which is viewed as an automorphism of the tensor product vertex operator superalgebra $…

Fusion products of twisted modules in permutation orbifolds

Chongying Dong, Haisheng Li, Feng Xu +1

Let $V$ be a vertex operator algebra, $k$ a positive integer and $σ$ a permutation automorphism of the vertex operator algebra $V^{\otimes k}$ . In this paper, we determine the fusi…
