Abstract

We discuss the non--perturbative formulation for c ≤ 1 string theory. The field theory like formulation of topological and non--topological models is presented. The integral representation for arbitrary (p,q) solutions is derived which explicitly obeys p-q duality of these theories. The exact solutions to string equation and various examples are also discussed.
