Spin Three-Body Problem of Classical Electrodynamics with Radiation Terms  (I) Derivation of Spin Equations

Abstract

In the present paper spin equations for three-body problem of classical electrodynamics are introduced. They should be considered jointly with 3-body equations of motion derived in a previous paper of the author. The system of spin equations is an overdetermined one. It is shown that the independent spin equations are nine in number as many as the components of the unknown spin functions. The system obtained will be solved by the xed-point method in a next paper.
