Cotensor decompositions for comodules over graded vertex operator coalgebras

Hao Wang

Let $V$ be a graded vertex operator coalgebra and $C$ the category of admissible $V$ -comodules. We first give the construction of contragredient comodule of an admissible…

A dual theory of twisted Zhu's theory

Hao Wang

The notion of admissible $g$ -twisted $V$ -comodules is investigated for a graded vertex operator coalgebra $V$ and a finite order automorphism $g\in \Aut V$. We prove that $\mathcal…

A dual theory of Zhu's theory

Hao Wang

We establish a dual theory of Zhu's $A (V)$ -theory, i.e., for a graded vertex operator coalgebra $V$ , the coassociative coalgebra $C (V)$ are investigated, any admissible…
