Regular rotating electrically charged black holes and solitons in nonlinear electrodynamics minimally coupled to gravity
Irina Dymnikova, Evgeny Galaktionov
In nonlinear electrodynamics coupled to gravity, regular spherically symmetric electrically charged solutions satisfy the weak energy condition and have obligatory de Sitter centre…
Multi-horizon spherically symmetric spacetimes with several scales of vacuum energy
Kirill Bronnikov, Irina Dymnikova, Evgeny Galaktionov
We present a family of spherically symmetric multi-horizon spacetimes with a vacuum dark fluid, associated with a time-dependent and spatially inhomogeneous cosmological term. The…
Stability of a vacuum nonsingular black hole
Irina Dymnikova, Evgeny Galaktionov
This is the first of series of papers in which we investigate stability of the spherically symmetric space-time with de Sitter center. Geometry, asymptotically Schwarzschild for la…
