On a Relativistically Invariant Formulation of the Quantum Theory of Wave Fields. III. Case of Interacting Electromagnetic and Electron Fields

Summary
We have thus shown that it is in fact possible to describe the behavior of the electromagnetic field interacting with electrons, in a perfectly relativistic form according to our general scheme developed in I. But if we wish to apply similar methods to more general cases, for instance, to the cases of the meson field interacting with the electromagnetic field or the nucleon field, some generalization is necessary. In fact, in the case of the quantum electrodynamics the situation is exceptionally
simple owing to the following two facts:
- (i)
- the interaction, energy density HI,II(P) is a scalar function of the fields and
- (ii)
- the integrability condition [HI,II(P),HI,II(P')] = 0 is satisfied from the beginning.
