A simple model for Poincaré self-stresses

This Issue Is Dedicated To The Memory Of Wolfgang Yourgrau


The classical theory of elementary charges as originally proposed by Abraham and Lorentz included implicitly a stability problem, which was first discussed by Poincaré in a very artificial way. It is shown that the consideration of nonlinear terms in the field Lagrangian densities provides the necessary cohesive forces in a natural way. Some examples of particle models are considered.
