The regular representation, Zhu's $A (V)$ -theory and induced modules

Haisheng Li

The regular representation is related to Zhu's $A (V)$ -theory and an induced module from an $A (V)$ -module to a $V$ -module is defined in terms of the regular representation. As an ap…

Regular representations of vertex operator algebras, I

Haisheng Li

In this paper, given a module $W$ for a vertex operator algebra $V$ and a nonzero complex number $z$ we construct a canonical (weak) $V \otimes V$ -module $D_{P (z)} (W)$ (a su…

On Z-graded associative algebras and their N-graded modules

Haisheng Li, Shuqin Wang

Let $A$ be a $Z$ -graded associative algebra and let $ρ$ be an irreducible $N$ -graded representation of $A$ on $W$ with finite-dimensional homogeneous subspaces. Then it is proved t…
