MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

The relativistic dynamics of the combined particle-field system in nonlinear renormalized electrodynamics

Hans-Peter Gittel, Jerzy Kijowski and Eberhard Zeidler

Abstract

This paper develops a general theory for the nonlinear interaction between a charged particle and an electromagnetic field. For the combined particle-field system, a fundamental relativistically invariant equation of motion is derived from first principles. This fundamental equation was first obtained in an alternative way by Kijowski in an earlier paper. It can be proved that the initial-value problem for the particle-field system is well-posed. The existence and uniqueness result is based on a careful analysis of the singularites of the electromagnetic field along the trajectory of the moving charged particle. Furthermore, the Banach fixed-point principle is used. This new theory improves the classical Dirac theory for the motion of electrons. In particular, it is shown how to exclude the Dirac paradox of runaway solutions having overlight speed.
