Automorphism groups and uniqueness of holomorphic vertex operator algebras of central charge
Koichi Betsumiya, Ching Hung Lam, Hiroki Shimakura
We describe the automorphism groups of all holomorphic vertex operator algebras of central charge with non-trivial weight one Lie algebras by using their constructions as simp…

Automorphism groups of cyclic orbifold vertex operator algebras associated with the Leech lattice and some non-prime isometries
Koichi Betsumiya, Ching Hung Lam, Hiroki Shimakura
We determine the automorphism groups of the cyclic orbifold vertex operator algebras associated with coinvariant lattices of isometries of the Leech lattice in the conjugacy classe…
