Escape from a black hole with spherical warp drive
Yury N. Eroshenko
In this paper, a class of the warp drive (WD) type metrics is proposed in the form of spherical and plane waves or shells. In particular, these metrics can describe the passage of…
On the cosmological solutions in Weyl geometry
Victor A. Berezin, Vyacheslav I. Dokuchaev, Yury N. Eroshenko +1
We investigated the possibility of construction the homogeneous and isotropic cosmological solutions in Weyl geometry. We derived the self-consistency condition which ensures the c…
Double layer in quadratic gravity and least action principle
V. A. Berezin, V. I. Dokuchaev, Yu. N. Eroshenko +1
The Israel equations for thin shells in General Relativity are derived directly from the least action principle. The method is elaborated for obtaining the equations for double lay…
Quadratic Gravity, double layers and non-conservative energy-momentum tensor
Victor A. Berezin, Vyacheslav I. Dokuchaev, Yury N. Eroshenko +1
In the present paper we investigate the conservative conditions in Quadratic Gravity. It is shown explicitly that the Bianchi identities lead to the conservative condition of the l…
Double layer from least action principle
V. A. Berezin, V. I. Dokuchaev, Yu. N. Eroshenko +1
We derived the equations for the double layers in Quadratic Gravity, using solely the least action principle. The advantage of our approach is that, in the process of calculation,…
Least action principle and gravitational double layer
Victor Berezin, Vyacheslav Dokuchaev, Yury Eroshenko +1
The higher derivative gravitational theories exhibit new phenomena absent in General Relativity. One of them is the possible formation of the so called double layer which is the pu…
