On abelian generalized vertex algebras
Haisheng Li
This paper studies the algebraic aspect of a general abelian coset theory with a work of Dong and Lepowsky as our main motivation. It is proved that the vacuum space (or th…
Generalized vertex algebras generated by parafermion-like vertex operators
Yongcun Gao, Haisheng Li
It is proved that for a vector space W, any set of parafermion-like vertex operators on W in a certain canonical way generates a generalized vertex algebra in the sense of [DL2] wi…
The regular representations and the algebras
Haisheng Li
For a vertex operator algebra , the regular representations are related to the -algebras and their bimodules, and induced -modules from -modules are defin…
Certain extensions of vertex operator algebras of affine type
Haisheng Li
We generalize Feigin and Miwa's construction of extended vertex operator (super)algebras for other types of simple Lie algebras. For all the constructed extended ver…
