Construction of a perfectly N-representable two-electron density matrix carrying full information on an interacting system.

The two-particle density matrix contains all information, which is "readable" by one- and two-particle operators. The report discusses the building of a two-electron density matrix, which is perfectly N-representable by construction. The 2-matrix of a pure quantum state is obtained without the intermediate determination of the wave function. The procedure is illustrated by computations on atomic and small molecular systems.
