Abstract
The problems involved in the determination of operator-product coefficients in nondiagonal conformal field theories are explained. The methods of Dotsenko and Fateev are used to derive formulas which allow one to compute these coefficients. A careful treatment of the issue of uniqueness of the results proves to be necessary.Keywords
