Abstract

The exact operator solution for quantum Liouville theory constructed for the generic quantum deformation parameter q is extended to the case with q being a root of unity. The screening charge operator becomes nilpotent in such cases and arbitrary Liouville exponentials can be obtained in finite polynomials of the screening charge.
