Abstract

The Ornstein-Zernike (OZ) equation for a hard core lattice gas limited by a planar hard wall is solved by means of an iterative procedure. The treatment is based on the existing analogy between the OZ equation and the lattice Green function equation governing a random walk on the lattice. Results are shown, within the Percus-Yevick approximation, for the density profile, the pair correlations and the surface tension.
