Abstract

It is shown that, in nonlinear (in particular, Born-Infeld) electrodynamics in the framework of general relativity, there exist “weakly singular” configurations such that (i) the proper mass M is finite despite divergences of the energy density, (ii) the electric charge q and the Schwarzschild mass m ∼ q can be made as small as one likes, and (iii) all field and energy distributions are concentrated in the core region. This region has an almost zero surface area but a finite longitudinal size L = 2M. Such configurations can be viewed as a new version of a classical analogue of an elementary particle.
