Representations of a class of lattice type vertex algebras
Stephen Berman, Chongying Dong, Shaobin Tan
In this paper we study the representation theory for certain ``half lattice vertex algebras.'' In particular we construct a large class of irreducible modules for these vertex alge…
On orbifold elliptic genus
Chongying Dong, Kefeng Liu, Xiaonan Ma
We define orbifold elliptic genus for general orbifolds which generalizes the definition of Borisov and Libgober, and prove their rigidity property.
Automorphism groups and derivation algebras of finitely generated vertex operator algebras
C. Dong, R. L. Griess
We investigate the general structure of the automorphism group and the Lie algebra of derivations of a finitely generated vertex operator algebra. The automorphism group is isomorp…
Vertex Lie algebras, vertex Poisson algebras and vertex algebras
C. Dong, H. Li, G. Mason
The notions of vertex Lie algebra and vertex Poisson algebra are presented and connections among vertex Lie algebras, vertex Poisson algebras and vertex algebras are discussed.
