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…

Fourvolutions and automorphism groups of orbifold lattice vertex operator algebras

Hsian-Yang Chen, Ching Hung Lam

Let $L$ be an even positive definite lattice with no roots, i.e., $L (2) = {x \in L ∣ (x ∣ x) = 2} = \emptyset$ . Let $g \in O (L)$ be an isometry of order $4$ such that $g^{2} = - 1$ on $L$ . In…
