On the "scattering law" for Kasner parameters in the model with one-component anisotropic fluid
V. D. Ivashchuk, V. N. Melnikov
A multidimensional cosmological type model with 1-component anisotropic fluid is considered. An exact solution is obtained. This solution is defined on a product manifold containin…
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…
Relation between confinement and higher symmetry restrictions for color particle motion
V. V. Khruschov
Quantum operators of coordinates and momentum components of a particle in the Minkowski spacetime can belong to the generalized Snyder-Yang algebra and produce a quantum phase spac…
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…
Models of G time variations in diverse dimensions
V. N. Melnikov
A review of different cosmological models in diverse dimensions leading to a relatively small time variation of the effective gravitational constant G is presented. Among them: 4-d…
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.,…
On cosmological-type solutions in multi-dimensional model with Gauss-Bonnet term
V. D. Ivashchuk
A (n + 1)-dimensional Einstein-Gauss-Bonnet (EGB) model is considered. For diagonal cosmological-type metrics, the equations of motion are reduced to a set of Lagrange equations. T…
On anisotropic Gauss-Bonnet cosmologies in (n+1) dimensions, governed by an n-dimensional Finslerian 4-metric
V. D. Ivashchuk
The (n +1)-dimensional Einstein-Gauss-Bonnet (EGB) model is considered. For diagonal cosmological metrics, the equations of motion are written as a set of Lagrange equations with t…
Symmetries of fundamental interactions in quantum phase space
V. V. Khruschov
Quantum operators of coordinates and momentum components of a particle in Minkowski space-time belong to a noncommutative algebra and give rise to a quantum phase space. Under some…
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…
Once again on thin-shell wormholes in scalar-tensor gravity
Kirill A. Bronnikov, Alexei A. Starobinsky
It is proved that all thin-shell wormholes built from two identical regions of vacuum static, spherically symmetric space-times have a negative shell surface energy density in any…
Cylindrical wormholes
Kirill A. Bronnikov, José P. S. Lemos
It is shown that the existence of static, cylindrically symmetric wormholes does not require violation of the weak or null energy conditions near the throat, and cylindrically symm…
