Cotensor decompositions for comodules over graded vertex operator coalgebras
Hao Wang
Let be a graded vertex operator coalgebra and the category of admissible -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 -twisted -comodules is investigated for a graded vertex operator coalgebra 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 -theory, i.e., for a graded vertex operator coalgebra , the coassociative coalgebra are investigated, any admissible…
Hopf actions on vertex operator algebras
Chongying Dong, Hao Wang
The Hopf actions on vertex operator algebras are investigated. If the action is semisimple, a Schur-Weyl type decomposition is obtained. When the Hopf algebra is finite dimensional…
Derivation algebras and automorphism groups of a class of deformative super -algebras
Hao Wang, Huanxia Fa, Junbo Li
In this paper, the derivation algebras and automorphism groups of a class of deformative super -algebras are determined.
Representations of Super algebra
Hao Wang, Huanxia Fa, Junbo Li
In paper, we study the representation theory of super algebra . We prove that has no mixed irreducible modules and give the classification…
