Multidimensional world, inflation and modern acceleration
K. A. Bronnikov, S. G. Rubin, I. V. Svadkovsky
Starting from pure multidimensional gravity with curvature-nonlinear terms but no matter fields in the initial action, we obtain a cosmological model with two effective scalar fiel…
Possible black universes in a brane world
K. A. Bronnikov, E. V. Donskoy
A black universe is a nonsingular black hole where, beyond the horizon, there is an expanding, asymptotically isotropic universe. Such spherically symmetric configurations have bee…
Spherical systems in models of nonlocally corrected gravity
K. A. Bronnikov, E. Elizalde
The properties of static, spherically symmetric configurations are considered in the framework of two models of nonlocally corrected gravity, suggested in S. Deser and R. Woodard.,…
Horizons in matter: black hole hair vs. Null Big Bang
K. A. Bronnikov, O. B. Zaslavskii
It is shown that only particular kinds of matter (in terms of the "radial" pressure to density ratio ) can coexist with Killing horizons in black-hole or cosmological space-time…
Wormholes supported by chiral fields
K. A. Bronnikov, S. V. Chervon, S. V. Sushkov
We consider static, spherically symmetric solutions of general relativity with a nonlinear sigma model (NSM) as a source, i.e., a set of scalar fields (so-called…
General static black holes in matter
K. A. Bronnikov, O. B. Zaslavskii
For arbitrary static space-times, it is shown that an equilibrium between a Killing horizon and matter is only possible for some discrete values of the parameter , where…
