Null-Cone Integral Formulation of Qed

Authors: Julian Brown

In these preliminary notes it is shown that the positive(negative) energy solutions of the Dirac equation also solve a specific integral equation over the past(future) null cone. It is shown that this integral equation yields the same scattering amplitudes as in the Feynman propagator picture, except for an intrinsic energy cutoff for emitted photons at $\omega_{max} = m_e$ due to the positive (negative) energy constraint imposed by the past(future) cone geometry. Fermionic self-energy is therefore finite and calculable.
