Conformal Blocks of Coset Construction: Zero Ghost Number

Abstract

It is shown that zero ghost conformal blocks of coset theory G/H are determined uniquely by those of G and H theories. G/G theories are considered as an example, their structure constants and correlation functions on sphere are calculated.
