Characterization of N-representable n-particle densities when N is infinite

Pistol, Mats-Erik LU (2006) In Chemical Physics Letters 417(4-6). p.521-523
Abstract
We have found necessary and sufficient conditions for the n-particle density to be N-representable for infinite A, if n is even. There are some mild restrictions on the one-density for these conditions to apply. The method is based on the Mercer expansion theorem. We suggest a simple method for total energy calculations based on this characterization also if the number of particles is finite. (c) 2005 Elsevier B.V. All rights reserved.
