. Using the Zhu algebra for a certain category of C -graded vertex algebras V , we prove that if V is finitely Ω -generated and satisfies suitable grading conditions, then V is rational, i.e. has semi-simple representation theory, with one dimensional level zero Zhu algebra. Here Ω denotes the vectors in V that are annihilated by lowering the real part of the grading. We apply our result to the family of rank one Weyl vertex algebras with conformal element ω µ parameterized by µ ∈ C , and prove…

{{C}}-Graded vertex algebras and conformal flow

We consider C-graded vertex algebras, which are vertex algebras V with a C-grading such that V is an admissible V-module generated by “lowest weight vectors.” We show that such vertex algebras have a

Vertex Operator Algebras Associated to Admissible Representations of

Abstract: The Kac-Wakimoto admissible modules for $\hat{sl}_2$ are studied from the point of view of vertex operator algebras. It is shown that the vertex operator algebra L(l,0) associated to

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

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

$C_2$-cofiniteness of the vertex algebra $V_L^+$ when $L$ is a non-degenerate even lattice

It was shown by Abe, Buhl and Dong that the vertex algebra $V_L^+$ and its irreducible weak modules satisfy the $C_2$-cofiniteness condition when $L$ is a positive definite even lattice. In this
