The physics superselection principle in vertex operator algebra theory
The author gives an application of the theory of superselection sectors in physics to vertex operator algebras. A construction of simple currents from a weight-one primary semisimple element has been introduced. As examples, the simple currents of the vertex operator algebras associated to affine Lie algebras and positive-definite even lattices are constructed.
