Point Charge in the Born-Infeld Electrodynamics

Abstract

We show that the nonlinear Born-Infeld field equations supplemented by the "dynamical condition" (certain boundary condition for the field along the particle's trajectory) define perfectly deterministic theory, i.e. particle's trajectory is determined without any equations of motion. It is a first step towards constructing the consistent theory of point particles interacting with nonlinear electromagnetism.
