Twisted modules for vertex algebras associated with vertex algebroids

Abstract

We continue with [LY] to construct and classify graded simple twisted modules for the $\mathbb{N}$-graded vertex algebras constructed by Gorbounov, Malikov and Schechtman from vertex algebroids. Meanwhile we determine the full automorphism groups of those $\mathbb{N}$-graded vertex algebras in terms of the automorphism groups of the corresponding vertex algebroids.
