Abstract. We give some general results about the generators and relations for the higher level Zhu algebras for a vertex operator algebra. In particular, for any element u in a vertex operator algebra V , such that u has weight greater than or equal to −n for n ∈ N, we prove a recursion relation in the nth level Zhu algebra An(V ) and give a closed formula for this relation. We use this and other properties of An(V ) to reduce the modes of u that appear in the generators for An(V ) as long as u…

Higher level Zhu algebras and modules for vertex operator algebras
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 higher level Zhu
Vertex operator algebras associated to representations of affine and Virasoro Algebras
The first construction of the integrable highest-weight representations of affine Lie algebras or loop algebras by Kac i-K] was greatly inspired by the generalization of the Weyl denominator formula
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
The Level One Zhu Algebra for the Heisenberg Vertex Operator Algebra
The level one Zhu algebra for the Heisenberg vertex operator algebra is calculated, and implications for the use of Zhu algebras of higher level for vertex operator algebras are discussed. In
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
Vertex Operator Algebras and Associative Algebras
LetVbe a vertex operator algebra. We construct a sequence of associative algebrasAn(V) (n = 0, 1, 2,…) such thatAn(V) is a quotient ofAn + 1(V) and a pair of functors between the category
Certain Generating Subspaces for Vertex Operator Algebras
Abstract Minimal generating subspaces of “weak PBW type” for vertex operator algebras are studied and a procedure is developed for finding such subspaces. As applications, some results on generalized
Some remarks on pseudo-trace functions for orbifold models associated with symplectic fermions
We give a method to construct pseudo-trace functions for vertex operator algebras satisfying Zhu's finiteness condition not through higher Zhu's algebras and apply our method to the Z_2-orbifold

TLDR
Here the authors haven’t even started the project yet, and already they’re forced to answer many questions: what will this thing be named, what directory will it be in, what type of module is it, how should it be compiled, and so on.
