Automorphism groups of parafermion vertex operator algebras: general case
Ching Hung Lam, Xingjun Lin, Hiroki Shimakura
We complete the program for determining the full automorphism groups of all parafermion vertex operator algebras associated with simple Lie algebras and positive integral levels. W…
On irreducibility of modules of Whittaker type: twisted modules and nonabelian orbifolds
Drazen Adamovic, Ching Hung Lam, Veronika Pedic Tomic +1
In arXiv:1811.04649, we extended the Dong-Mason theorem on irreducibility of modules for cyclic orbifold vertex algebras to the entire category weak modules and applied this result…
On irreducibility of modules of Whittaker type for cyclic orbifold vertex algebra
Drazen Adamovic, Ching Hung Lam, Veronika Pedic Tomic +1
We extend the Dong-Mason theorem on the irreducibility of modules for orbifold vertex algebras from [C. Dong, G. Mason, Duke Math. J. 86 (1997)] 305-321] for the category of weak m…
Reverse orbifold construction and uniqueness of holomorphic vertex operator algebras
Ching Hung Lam, Hiroki Shimakura
In this article, we develop a general technique for proving the uniqueness of holomorphic vertex operator algebras based on the orbifold construction and its "reverse" process. As…
Residue codes of extremal Type II Z_4-codes and the moonshine vertex operator algebra
Masaaki Harada, Ching Hung Lam, Akihiro Munemasa
In this paper, we study the residue codes of extremal Type II Z_4-codes of length 24 and their relations to the famous moonshine vertex operator algebra. The main result is a compl…
