Relativistic equations of Faddeev type are formulated in momentum space for three identical fermions. They are based on the so-called spectator approach, in which spectator particles are consistently placed on mass shell. Although the equations involve only three-dimensional integrations, they are mainifestly covariant. They satisfy the properties of cluster separability, three-body unitary, and in their non-relativistic limit they reproduce exactly the familiar non-relativistic Faddeev equations. The spectator equations are applied to the case of the three-nucleon bound state. The effect of Lorentz boosts and Wigner spin rotations on the three-nucleon binding energy is studied. First numerical results for a complete non-perturbative solution of the spectator equations are presented. They are based on relativistic two-nucleon potentials that have been constructed consistently within the spectator approach.
