"Particle-like" singular solutions in Einstein-Maxwell theory and in algebraic dynamics

Abstract

Foundations of algebrodynamics based on earlier proposed equations of biquaternionic holomorphy are briefly expounded. Free Maxwell and Yang-Mills Eqs. are satisfied identically on the solutions of primary system which is also related to the Eqs. of shear-free null congruences (SFC), and through them - to the Einstein-Maxwell electrovacuum system. Kerr theorem for SFC reduces the basic system to one algebraic equation, so that with each solution of the latter some (singular) solution of vacuum Eqs. may be associated. We present some exact solutions of basic algebraic and of related field Eqs. with compact structure of singularities of electromagnetic field, in particular having the form of figure "8" curve. Fundamental solution to primary system is analogous to the metric and fields of the Kerr-Newman solution. In addition, in the framework of algebraic dynamics the value of electric charge for this solution is strictly fixed in magnitude and may be set equal to the elementary charge.
