Conformal sigma models corresponding to gauged Wess-Zumino - Witten theories
We develop a field-theoretic approach to determination of the background target space fields corresponding to general $G/H$ coset conformal theories described by gauged WZW models. The basic idea is to identify the effective action of a gauged WZW theory with the effective action of a sigma model. T...
