| Abstract: | The relation between multiparticle Schrödinger equations and the underlying field theory for weakly coupled systems is clarified. A systematic perturbation theory for the energy levels is presented the first term of which is the eigenvalue of a Schrödinger equation with relativistic kinematics. |
