Some quantum vertex algebras of Zamolodchikov-Faddeev type
Martin Karel, Haisheng Li
This is a continuation of a previous study of quantum vertex algebras of Zamolodchikov-Faddeev type. In this paper, we focus our attention on the special case associated to diagona…

Certain generating subspaces for vertex operator algebras
Martin Karel, Haisheng Li
We study minimal generating subspaces of "weak PBW type" for vertex operator algebras that satisfy a certain condition on the grading, and we develop a procedure for finding such s…
