Vertex operator algebras, extended E_8 diagram, and McKay's observation on the Monster simple group
Ching Hung Lam, Hiromichi Yamada, Hiroshi Yamauchi
We study McKay's observation on the Monster simple group, which relates the 2A-involutions of the Monster simple group to the extended E_8 diagram, using the theory of vertex opera…

2A-orbifold construction and the baby-monster vertex operator superalgebra
Hiroshi Yamauchi
In this article we prove that the full automorphism group of the baby-monster vertex operator superalgebra constructed by Hoehn is isomorphic to 2xB, where B is the baby-monster sp…
