  We solved the three-nucleon Faddeev equation including relativistic features
such as relativistic kinematics, boost effects and Wigner spin rotations. As
dynamical input a relativistic nucleon-nucleon interaction exactly on-shell
equivalent to the AV18 potential has been used. The effects of Wigner rotations
for elastic scattering observables were found to be small. The boost effects
are significant at higher energies.They diminish the transition matrix elements
at higher energies and lead in spite of the increased relativistic phase-space
factor as compared to the nonrelativistic one to rather small effects in the
cross section, which are mostly restricted to the backward angles.
