RELATIVISTIC GENERALIZATION OF MANY-BODY CORRELATION DYNAMICS

With the aid of generating-functional technique, the many-body correla tion dynamics was generalized to the relativistic cases within a Green 's function formalism and two sets of equations of motion for the corr elation (or connected) Green's functions were derived respectively for the scalar phi3-model and the Yukawa model, which were nonperturbativ e in nature and could provide physically transparent truncations with respect to the order of correlations.
