Dirac’s Monopoles and Action-at-a-Distance Theory: Classical Dynamics Dirac’s Monopoles and Action-at-a-Distance Theory: Classical Dynamics 平田, 光司 ヒラタ, コウジ HIRATA, Koji 平田 ヒラタ HIRATA 光司 コウジ Koji HIRATA, Kohji metadata only access © 1980 Published by Elsevier B.V. We redefine Dirac's action for charge-monopole systems as a certain limit of Wu-Yang's action in a way which is similar to, but different from, the work of Brandt and Primack. The lagrangian theory thus obtained reproduces, in a simple and straightforward manner, all of the Maxwell-Lorentz equations without recourse to Dirac's veto. It also becomes clear that the action-at-a-distance formalism is especially suited for the description of such systems. An action, equations of motion and conserved linear and angular momenta are explicitly given, which do not depend on the string. The existence of a charge-monopole bound state is suggested.
