Abstract. By using a supersymmetric Gaussian representation, we transform the averaged Green's function for random walks in random potentials into a 2-point correlation function of a correponding lattice field theory. We study the resulting lattice field theory using the Witten Laplacian formulation. We obtain the asymptotics for the directional Lyapunov exponents.
