✦ Synopsis

A modification of the electromagnetic field is examined, servi.ng only. as a calculation model for a point charge.

Introductio'n. Simple classical models of the electron are still of interest for the difficulties in the quantum theory. They show typical difficulties themselves. A point charge leads to infinities. A structure of finite extension meets difficulties in a relativistic invariant description. It also requires the introduction of a non-electromagnetic energy-momentum tensor. In this note a model of a point charge is mentioned with a slightly modi;fied electromagnetic field. A fundamental interval of time is introduced, which is the counterpart in coordinate space of the fundamental mass in the Yukawa-Proca interaction field in momentum space. This is explained in the appendix.
