Abstract
Approximation schemes are investigated for the average Green function for a high-density disordered system in the Gaussian approximation, using a path-integral approach. The density of states is found for a one-dimensional system of delta functions, as well as for a distribution of three-dimensional screened Coulomb potentials.Keywords
