摘要： Recently, G. Hoehn has proposed a method for constructing all holomorphic vertex operator algebras in Schellekens' list  using the Leech lattice.  His idea is in some sense a generalization of the theory of Cartan subalgebras to VOA. The main idea is to study the commutant subVOA of the subVOA generated by a Cartan subalgebra of $V_1$ and try to construct a holomorphic VOA using certain simple current extensions of lattice VOAs and some orbifold subVOAs in the Leech lattice VOA.In this talk, we will explain his idea in detail and try to realize his proposed constructions.
