✦ Synopsis

The technique of the decomposed Feynman propagator is used to establish the equivalence between the Feynman and field theoretic formalisms. It is shown that for an nth order process, each of the 2 ~ 1 decomposed Feynman diagrams is equivalent to a certain group in the n! field theoretic diagrams_ This is demonstrated for the fourth order Compton scattering of an electron by identifying the energy denominators in the two formalisms.
