Abstract
The partial-wave dispersion relation for the nucleon-nucleon scattering is proved in every order of perturbation theory. A partial-wave dispersion relation for the pion-nucleon scattering is proved only for the graphs in which the two external pion lines are attached to the nucleon open polygon.Keywords
