We present a self-consistent quantum-mechanical formulation of the nonlocal dynamical
potential near the surface of a solid describable in a coordinate system in which Laplace
equation is separable. We apply the formulation to calculate image potential on surfaces
with uniform curvature, i.e. planar, spherical and cylindrical surfaces. We also calculate
the dielectric function e(w) and
dispersion relations of surface modes in these systems.
