Rank One Lattice Type Vertex Operator Algebras and Their Automorphism Groups

Abstract

Let L be a positive definite even lattice of rank one andV+Lbe the fixed points of the lattice VOAVLassociated to L under an automorphism ofVLlifting the -1 isometry of L. A set of generators and the full automorphism group ofV+Lare determined. © 1998 Academic Press.
