Abstract

A geometric description of the Lienard-Wiechert field of a single point charge is given. The dual of the Lienard-Wiechert field can be considered as the curvature in a bundle of 2-planes distributed smoothly over space-time. This geometric construction also accounts for the Teitel-boim splitting of the total field into bound and radiative parts: The radiation field can be identified with the curvature in the normal bundle. Various questions concerning potentials and the in-tegrability of the distributions involved are discussed. Whereas the intrinsic symmetry group for the field is that of the 2-plane bundle, namely SO (2), the normal bundle approach leads to the group SO (1,1) as the internal symmetry group for the radiation field.
