Modular Virasoro Vertex Algebras and Affine Vertex Algebras
Xiangyu Jiao, Haisheng Li, Qiang Mu
In this paper, we study Virasoro vertex algebras and affine vertex algebras over a general field of characteristic . More specifically, we study certain quotients of the unive…

Symmetric Invariant Bilinear Forms on Modular Vertex Algebras
Haisheng Li, Qiang Mu
In this paper, we study contragredient duals and invariant bilinear forms for modular vertex algebras (in characteristic ). We first introduce a bialgebra and we t…
