On orbifold constructions associated with the Leech lattice vertex operator algebra

Abstract

In this article, we study orbifold constructions associated with the Leech lattice vertex operator algebra. As an application, we prove that the structure of a strongly regular holomorphic vertex operator algebra of central charge $24$ is uniquely determined by its weight one Lie algebra if the Lie algebra has the type $A_{3,4}^3{A}_{1,2}$, $A_{4,5}^2$, $D_{4,12}{A}_{2,6}$, $A_{6,7}$, $A_{7,4}{A}_{1,1}^3$, $D_{5,8}{A}_{1,2}$ or $D_{6,5}{A}_{1,1}^2$ by using the reverse orbifold construction. Our result also provides alternative constructions of these vertex operator algebras (except for the case $A_{6,7}$) from the Leech lattice vertex operator algebra.
