Analysis of regularizing properties of nonlinear electrodynamics in the Einstein-Born-Infeld theory

摘要

New regularizing manifestations of the Einstein-Born-Infeld theory for a massive charged force center in the space-time are considered. The properties of isotropic geodesics in this space are analyzed. It is shown that the charge may exceed the maximum possible charge in the Reissner-Nordstr?m solution; the possibility of eliminating one of the metric horizons is also noted.
