Let us first expose the foundation of the Hartree-Fock method in a simple case where the particles have no spin (or are all in the same individual spin state) so that no spin quantum number is needed to define their individual states, specified by their wave functions. We introduce the notation and define the trial family of the N-particle state vectors.
