Abstract: 
A model of nonlinear electrodynamics with two parameters, coupled with general relativity, is investigated. We study the magnetized black hole and obtain solutions. The asymptotic of the metric and mass functions at r→∞ and r→0, and corrections to the Reissner-Nordstrom solution are found. We investigate thermodynamics of black holes and calculate the Hawking temperature and heat capacity of black holes. It is shown that there are phase transitions and at some parameters of the model black holes are stable.

Foundations of the new field theory

TL;DR: The relation of matter and the electromagnetic field can be interpreted from two opposite standpoints as discussed by the authors : the unitarian viewpoint assumes only one physical entity (e.g., a single unitary entity) and the second viewpoint assumes that all particles of matter are considered as singularities of the field and mass is a derived notion expressed by field energy (electromagnetic mass).

Formation and Evaporation of Nonsingular Black Holes

Sean A. Hayward
- 26 Jan 2006 - 
TL;DR: Regular (nonsingular) space-times are given that describe the formation of a (locally defined) black hole from an initial vacuum region, its quiescence as a static region, and its subsequent evaporation to a vacuum region.
