On certain categories of modules for twisted affine Lie algebras
Yongcun Gao, Jiayuan Fu
We classify integrable irreducible -modules in categories E and C, where E is proved to contain the well known evaluation modules and C to unify highest weight modules,…

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…
