Irreducible modules of toroidal Lie algebras arising from $ϕ_{ε}$ -coordinated modules of vertex algebras

Fulin Chen, Huansheng Li, Nina Yu

In this paper, for every $ε \in Z$ , we introduce an extension of the 2-toroidal Lie algebra by certain derivations. Based on the $ϕ_{ε}$ -coordinated modules theory for vertex…

On a family of vertex operator superalgebras

Haisheng Li, Nina Yu

This paper is to study vertex operator superalgebras which are strongly generated by their weight- $2$ and weight- $\frac{3}{2}$ homogeneous subspaces. Among the main results, it is…

Extended affine Lie algebras, vertex algebras and equivariant $ϕ$ -coordinated quasi modules

Fulin Chen, Shaobin Tan, Nina Yu

For any nullity $2$ extended affine Lie algebra $E$ of maximal type and $ℓ \in C$ , we prove that there exist a vertex algebra $V_{E} (ℓ)$ and an aut…

Permutation orbifolds and associative algebras

Chongying Dong, Feng Xu, Nina Yu

Let $V$ be a vertex operator algebra and $g = (12 \dots k)$ be a $k$ -cycle which is viewed as an automorphism of the vertex operator algebra $V^{\otimes k}$ . It is pro…

$6 A$ -Algebra and its representations

Chongying Dong, Xiangyu Jiao, Nina Yu

In this paper, we study the structure and representation of a $6 A$ -algebra which is a vertex operator algebra generated by two Ising vectors $e, f$ with inner product $\left\langle…

Simple Whittaker modules over free bosonic orbifold vertex operator algebras

Jonas T. Hartwig, Nina Yu

We construct weak (i.e. non-graded) modules over the vertex operator algebra $M (1)^{+}$ , which is the fixed-point subalgebra of the higher rank free bosonic (Heisenberg) vertex opera…
