โฆ Synopsis
In a free-electron laser set up as a single-pass amplifier, the evolution of the optical beam in the weak-field regime is ruled by the so-called Integral Equation. We derive this equation by a different analytical technique with respect to the one employed in earlier works. Our approach proves to be mathematically simpler and more physically transparent with respect to the original one.

We construct a new kind of path integral for the Dirac equation propagator, intended as an extension to 3 space dimensions of the Feynman ``checkerboard'' propagator. One form of this path integral is a ``projector path'' summation, out of which one can reconstruct standard 3D space and chirality. O
