The conventional formulation of quantum electrodynamics in which the system develops from one space-like hyperplane to the next is here replaced by one in which the development proceeds over null hyperplanes. For detailed study a quantized electromagnetic field ${A}^{\ensuremath{\mu}}$ is chosen to interact with a quantized spin-0 particle field $\ensuremath{\Phi}$ in an unquantized electromagnetic field $A_{\mathrm{ext}}^{}{}_{}{}^{\ensuremath{\mu}}$ as background. If the latter is chosen to… CONTINUE READING
