Ising vectors and automorphism groups of commutant subalgebras related to root systems
Ching Hung Lam, Shinya Sakuma, Hiroshi Yamauchi
In this article we study and obtain a classification of Ising vectors in vertex operator algebras associated to binary codes and times root lattices, where an Ising vect…

McKay's observation and vertex operator algebras generated by two conformal vectors of central charge 1/2
Ching Hung Lam, Hiromichi Yamada, Hiroshi Yamauchi
This paper is a continuation of our paper math.QA/0403010 at which several coset subalgebras of the lattice VOA were constructed and the relationship between such…

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…
