Rank one lattice type vertex operator algebras and their automorphism groups
Chongying Dong, Robert L. Griess
Let L be a positive definite even lattice of rank one and V_L^+ be the fixed points of the lattice VOA V_L associated to L under an automorphism of V_L lifting the -1$ isometry of…
Framed vertex operator algebras, codes and the moonshine module
C. Dong, R. L. Griess, G. Hoehn
For a simple vertex operator algebra whose Virasoro element is a sum of commutative Virasoro elements of central charge 1/2, two codes are introduced and studied. It is proved that…
Modular invariance of trace functions in orbifold theory
Chongying Dong, Haisheng Li, Geoffrey Mason
The goal of the present paper is to provide a mathematically rigorous foundation to certain aspects of rational orbifold conformal field theory, in other words the theory of ration…
Twisted representations of vertex operator algebras and associative algebras
C. Dong, H. Li, G. Mason
Let V be a vertex operator algebra and g an automorphism of order T. We construct a sequence of associative algebras A_{g,n}(V) with n\in\frac{1}{T}\Z nonnegative such that A_{g,n}…
Vertex operator algebras and associative algebras
Chongying Dong, Haisheng Li, Geoffrey Mason
Let V be a vertex operator algebra. We construct a sequence of associative algebras A_n(V) (n=0,1,2,...) such that A_{n}(V) is a quotient of A_{n+1}(V) and a pair of functors betwe…
