Abstract

Based on the Hohenberg-Kohn theorem, an exact integral expression is derived, which relates the nonuniform density to the inverse response function in the equilibrium system of interacting electrons. This relation is a necessary condition for the existence of the universal density functional in the density functional theory. The possibility of developing a regular procedure for calculating the density functional for the free energy or ground-state energy is shown.
