Outline of Final Research Achievements

A rank 1, type A, level k parafermion vertex operator algebra is defined as the commutant of the Heisenberg algebra in the integrable representation of a rank 1, type A affine Lie algebra at level k, which is a C2-cofinite and rational vertex operator algebra. The parafermion vertex operator algebra has k simple currents and there is a Zk-symmetry in the fusion rules among them. Using a Zk-code and those simple currents, a new series of C2-cofinite and rational vertex operator algebras is constructed.
