Lattice vertex algebras of type ADE over fields of prime characteristic and their representations

Qiang Mu, Hongju Zhao

We study lattice vertex algebras of type ADE over an algebraically closed field $F$ of prime characteristic $p > 2$ and their representations. Let $L$ be a root lattice of t…

Twisted modules of $\frac{1}{2} Z$ -graded modular vertex superalgebras

Xiangyu Jiao, Qiang Mu, Wei Wang

In this paper, we investigate the theory of $g$ -twisted modules for modular $\frac{1}{2} Z$ -graded vertex superalgebras over an algebraically closed field $F$ of p…

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 $p > 2$ . 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 $p$ ). We first introduce a bialgebra $H$ and we t…
