| Abstract: | In this paper, we define excited states for Coulomb systems in the Hartree-Fock approximation as minima of the Hartree-Fock energy on a set of constraints depending on excited states of the lower energy. There are several ways to define such a procedure: we study four of them and prove an existence result for these excited states. |
