A U1 PRINCIPAL BUNDLE THEORY FOR THE BORN-INFELD ELECTRODYNAMICS
Born-Infeld电动力学的U1主丛表述

A U1-bundle formalism for the Born-Infeld electrodynamics is proposed and the equation of motion for a test particle in the Born-Infeld electromagnetic field is given. There are two forces acting on the test particle, one corresponds to the Lorentz force and the other the Poincaré stress.
