Abstract Exact representations of generating functional of one‐component systems with arbitrary central interatomic potentials via functional integral over auxiliary field defined in wave‐vector space are obtained. It is proved that the problem of partition function evaluation is equivalent to the problem of statistical integral of nonlinear (self‐acting) temperature‐dependent field. Elementary excitations Hamiltonian for the continuous model of the classical statistical physics from “first principles” is obtained. © 2003 Wiley Periodicals, Inc. Int J Quantum Chem, 2004
