SEMICLASSICAL BLOCKS AND CORRELATORS IN RATIONAL AND IRRATIONAL CONFORMAL FIELD-THEORY

The generalized Knizhnik-Zamolodchikov equations of irrational conform al field theory provide a uniform description of rational and irration al conformal field theory. Starting from the known high-level solution of these equations, we first construct the high-level conformal block s and correlators of all the affine-Sugawara and coset constructions o n Simple g. Using intuition gained from these cases, we then identify a simple class of irrational processes whose high-level blocks and cor relators we are also able to construct.
