内容摘要： 

In this paper, we study contragredient duals and invariant bilinear

forms for modular vertex algebras (in characteristic p). We first

introduce a bialgebra H and we then introduce a notion of H-module

vertex algebra and a notion of (V;H)-module for an H-module vertex

algebra V . Then we give a modular version of Frenkel-Huang-Lepowsky's

theory and study invariant bilinear forms on an H-module vertex

algebra. As the main results, we obtain an explicit description of the

space of invariant bilinear forms on a general H-module vertex

algebra, and we apply our results to affine vertex algebras and

Virasoro vertex algebras. This is joint work with Professor Haisheng

Li.
