Abstract: We derive an equation for the time evolution of the natural occupation numbers for fermionic systems with more than two electrons. The evolution of such numbers is connected with the symmetry-adapted generalized Pauli exclusionprinciple, as well as with the evolution of the natural orbitals and a set of many-body relative phases. We then relate the evolution of these phases to a dynamical and a correlated term, attached to each one of the Slater determinants appearing in the configuration-interaction expansion of the wave function.
