Some chiral rings of N = 2 discrete superconformal series induced by SL(2) degenerate conformal field theories Original Research Article

By generalizing a fermionic construction a natural relation is found between SL(2) degenerate conformal field theories and some N = 2 discrete superconformal series. These non-unitary models contain, as a subclass, N = 2 minimal models. The construction permits one to investigate the properties of chiral operators in the N = 2 models. A chiral ring reveals a close connection with the underlying quantum group structures.
