Variational electrodynamics

Abstract

We shall study the electromagnetic two-body problem with a variational principle. The variational principle completes and generalizes Wheeler-Feynman electrodynamics by incorporating trajectories with discontinuous velocities, necessary for the variational boundary-value problem to have a solution with arbitrary boundary data. The generalization is also necessary physically, to describe two-body orbits with vanishing far-fields defined almost everywhere. We shall study the complex physical dynamics involving equations of motion defined piecewise plus the continuity of a long-range current involving the vector potential of the other charges. (AU)
