Shifted Vertex Operator Algebras
Chongying Dong, Geoffrey Mason
We study the properties of shifted vertex operator algebras, which are vertex algebras derived from a given theory by shifting the conformal vector. In this way, we are able to exh…

Local and Semilocal Vertex Operator Algebras
Chongying Dong, Geoffrey Mason
We investigate a general structure theory for a vertex operator algebra. We discuss the center and blocks, the Jacobson radical and solvable radical and local vertex operator algeb…

Central Invariants and Frobenius-Schur Indicators for Semisimple Quasi-Hopf Algebras
Geoffrey Mason, Siu-Hung Ng
In this paper, we obtain a canonical central element for each semi-simple quasi-Hopf algebra over any field and prove that is invariant under gauge transformati…
