Simple Toroidal Vertex Algebras and Their Irreducible Modules

Fei Kong, Haisheng Li, Shaobin Tan +1

In this paper, we continue the study on toroidal vertex algebras initiated in \cite{LTW}, to study concrete toroidal vertex algebras associated to toroidal Lie algebra $L_{r}(\hat{…

$q$ -Virasoro algebra and vertex algebras

Hongyan Guo, Haisheng Li, Shaobin Tan +1

In this paper, we study a certain deformation $D$ of the Virasoro algebra that was introduced and called $q$ -Virasoro algebra by Nigro,in the context of vertex algebras. Among the…

$ϕ_{ε}$ -coordinated modules for vertex algebras

Chengming Bai, Haisheng Li, Yufeng Pei

We study $ϕ_{ε}$ -coordinated modules for vertex algebras, where $ϕ_{ε}$ with $ε$ an integer parameter is a family of associates of the one-dimensional additive formal group. As the mai…
