    • Abstract

       

      In connection with the quantum-mechanical variation principle, it is shown that the Brillouin theorem and the stability conditions usually associated with the Hartree-Fock scheme in the many-electron theory may be generalized to the case of arbitrary trial functions depending on a set of linear or non-linear complex parameters.
