We study and classify systems of certain screening operators arising in a generalized vertex operator algebra, or more generally an abelian intertwining algebra with an associated vertex operator (super)algebra. Screening pairs arising from weight one primary vectors acting commutatively on a lattice vertex operator algebra (the vacuum module) are classified into four general types; one type of which has been shown to play an important role in the construction and study of certain important… 



Screening Operators for Lattice Vertex Operator Algebras and Resulting Constructions

by Nathan P. Vander Werf We give a rigorous treatment of the notion of screening pairs of screening operators (Q̃, Q) for a rank d lattice vertex operator superalgebra VL. Certain such screening

Lattice construction of logarithmic modules for certain vertex algebras

A general method for constructing logarithmic modules in vertex operator algebra theory is presented. By utilizing this approach, we give explicit vertex operator construction of certain

Modular invariance of vertex operator algebras satisfying $C_{2}$-cofiniteness

We show that C_2-cofiniteness is enough to prove a modular invariance property of vertex operator algebras without assuming the semisimplicity of Zhu algebra. For example, if a VOA

An explicit realization of logarithmic modules for the vertex operator algebra W_{p,p'}

By extending the methods used in our earlier work, in this paper, we present an explicit realization of logarithmic $\mathcal{W}_{p,p'$}-modules that have L(0) nilpotent rank three. This was achieved

On the Extended W-Algebra of Type 2 at Positive Rational Level

The extended W-algebra of type sl2 at positive rational level, denoted by Mp+,p− , is a vertex operator algebra (VOA) that was originally proposed in [16]. This VOA is an extension of the

Representation theory of finite W algebras

In this paper we study the finitely generated algebras underlyingW algebras. These so called ’finite W algebras’ are constructed as Poisson reductions of Kirillov Poisson structures on simple Lie

Modular invariance of characters of vertex operator algebras

In contrast with the finite dimensional case, one of the distinguished features in the theory of infinite dimensional Lie algebras is the modular invariance of the characters of certain
