Abstract
We discuss the appearance of spurious solutions of few-body equations for F addeev amplitudes. The identification of spurious states, i.e., states that lack the symmetry required fdr solutions of the Schrodinger equation, as w ell as the symmetrization of the Faddeev equations is investigated. As an e xample, systems of three and four electrons, bound in a harmonic-oscillator potential and interacting by the Coulomb potential, are presented. [S0556- 2813(99)05002-5].
