Nonlinear Theory of Elementary Particles Part VII: Classical Nonlinear Electron Theories and Their Connection with QED

Abstract

In this article of nonlinear theory of elementary particles (NTEP) a review of the nonlinear field theories in the framework of classical electrodynamics is presented. It is shown that the results found within these theories can be transferred to quantum theory. These results can also help us to understand many aspects of the quantum description of elementary particles. In particular, they explain why electron can be interpreted as a point and non-point particle simultaneously.
