Restricted modules for gap- Virasoro algebra and twisted modules for certain vertex algebras
Hongyan Guo, Chengkang Xu
This paper studies restricted modules of gap- Virasoro algebra and their intrinsic connection to twisted modules of certain vertex algebras. We first establish an equivalenc…

q-Virasoro algebra and affine Kac-Moody Lie algebras
Hongyan Guo, Haisheng Li, Shaobin Tan +1
We establish a natural connection of the -Virasoro algebra introduced by Belov and Chaltikian with affine Kac-Moody Lie algebras. More specifically, for each abelian gro…
