Coset conformal field theories with abelian isotropy groups
Abstract
Description
Conformal field theories based on $g/u(1)^d$ coset constructions where $g$ is a reductive algebra are studied.It is shown that the theories are equivalent to constrained WZNW models for $g.$ Generators of extended symmetry algebras and primary fields are constructed.
