On stable exponential solutions in Einstein-Gauss-Bonnet cosmology with zero variation of G
V. D. Ivashchuk
A D-dimensional gravitational model with a Gauss-Bonnet term and the cosmological term Lambda is considered. Assuming diagonal cosmological metrics, we find, for certain non-zero L…
Wormholes and black universes communicated with extra dimensions
K. A. Bronnikov, P. A. Korolyov, A. Makhmudov +1
In 6D general relativity with a phantom scalar field as a source of gravity, we present solutions that implement a transition from an effective 4D geometry times small extra dimens…
Cosmology in nonlinear multidimensional gravity and the Casimir effect
S. V. Bolokhov, K. A. Bronnikov
We study the possible cosmological models in Kaluza-Klein-type multidimensional gravity with a curvature-nonlinear Lagrangian and a spherical extra space, taking into account the C…
Wormholes leading to extra dimensions
K. A. Bronnikov, M. V. Skvortsova
In 6D general relativity with a scalar field as a source of gravity, a new type of static wormhole solutions is presented: such wormholes connect our universe with a small 2D extra…
Wormholes and black universes without phantom fields in Einstein-Cartan theory
K. A. Bronnikov, A. M. Galiakhmetov
We obtain a family of regular static, spherically symmetric solutions in Einstein--Cartan theory with an electromagnetic field and a nonminimally coupled scalar field with the corr…
Static, spherically symmetric solutions with a scalar field in Rastall gravity
K. A. Bronnikov, J. C. Fabris, O. F. Piattella +1
Rastall's theory belongs to the class of non-conservative theories of gravity. In vacuum, the only non-trivial static, spherically symmetric solution is the Schwarzschild one, exce…
The Birkhoff theorem and string clouds
K. A. Bronnikov, Sung-Won Kim, M. V. Skvortsova
We consider spherically symmetric space-times in GR under the unconventional assumptions that the spherical radius is either a constant or has a null gradient in the su…
On Black Hole Structures in Scalar-Tensor Theories of Gravity
Kirill A. Bronnikov, Júlio C. Fabris, Denis C. Rodrigues
We review some properties of black hole structures appearing in gravity with a massless scalar field, with both minimal and nonminimal coupling. The main properties of the resultin…
On multidimensional solutions in the Einstein-Gauss-Bonnet model with a cosmological term
A. A. Kobtsev, V. D. Ivashchuk, K. K. Ernazarov
A D-dimensional gravitational model with Gauss-Bonnet and cosmological term is considered. When ansatz with diagonal cosmological metrics is adopted, we overview recent solutions f…
