The level two Zhu algebra for the Heisenberg vertex operator algebra

Darlayne Addabbo, Katrina Barron

We determine the level two Zhu algebra for the Heisenberg vertex operator algebra $V$ for any choice of conformal element. We do this using only the following information for $V$ :…

Classification of screening systems for lattice vertex operator algebras

Katrina Barron, Nathan Vander Werf

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…

Higher level Zhu algebras and modules for vertex operator algebras

Katrina Barron, Nathan Vander Werf, Jinwei Yang

Motivated by the study of indecomposable, nonsimple modules for a vertex operator algebra $V$ , we study the relationship between various types of $V$ -modules and modules for the hi…

Permutation-twisted modules for even order cycles acting on tensor product vertex operator superalgebras

Katrina Barron, Nathan Vander Werf

We construct and classify $(12 \dots k)$ -twisted $V^{\otimes k}$ -modules for $k$ even and $V$ a vertex operator superalgebra. In particular, we show that the category of…
