    Graduate Understanding Electron Mass in Classical and Quantum Electrodynamics

    Consider classical electron theory. Distinguish between the mechanical, electromagnetic, and observed electron mass. What is the degree of divergence of the classical electron self-energy? What are the roles of mass-renormalization, runaway solutions, and preacceleration in classical electron...
