Schwinger’s equation for one-body propagator of a selfcoupled spinor field
Journal Article

· Acta Physica Academiae Scientiarum Hungaricae
The enormalization problems of the Thirring model, completed by a meson- fermion derivative coupling, was previously investigated, and the many-particle propagators originating from the derivative coupling were determined by means of a non perturbative treatment. The nonperturbative treatment of the self-coupled spinor field must still be considered. As a preliminary step the Schwinger equation of the one-body propagator was deduced by a nonperturbative method. The external source method was used. As the equation obtained shows some features which differ from those of the corresponding equations of quantum electrodynamics and meson theories, the Schwinger equation must be of the second order.
