Abstract

A review of the operator Padé approach to the summation of perturbation theory of quantum field theory is given. It is shown that the method yields solutions of the Schrödinger- and the Bethe-Salpeter-equation as special cases. Applications are given for the Nucleon-Nucleon scattering in terms of the Bethe-Salpeter equation in ladder approximation and a renormalizable gauge field theory including π-, ρ- and w-exchange.
