ABSTRACT

In this article, we discuss a more uniform construction of all $71$ holomorphic vertex operator algebras in Schellekens' list using an idea proposed by G. H\"ohn. The main idea is to try to construct holomorphic vertex operator algebras of central charge $24$ using some sublattices of the Leech lattice $\Lambda$ and level $p$ lattices. We study his approach and try to elucidate his ideas. As our main result, we prove that for an even unimodular lattice $L$ and a prime order isometry $g$, the orbifold vertex operator algebra $V_{L_g}^{\hat{g}}$ has group-like fusion. We also realize the construction proposed by H\"ohn for some special isometry of the Leech lattice of prime order.
