Conformally-flat Stackel spaces in Brans-Dicke theory

V. V. Obukhov, K. E. Osetrin, A. E. Filippov +1

The classification problem for conformally-flat space-times that admit a separation of variables in the Hamilton-Jacobi equation of the scalar-tensor Brans-Dicke theory of gravity…

Horizons vs. singularities in spherically symmetric space-times

K. A. Bronnikov, E. Elizalde, S. D. Odintsov +1

We discuss different kinds of Killing horizons possible in static, spherically symmetric configurations and recently classified as "usual", "naked" and "truly naked" ones depending…

A FRW Dark Fluid with a Non-Linear Inhomogeneous Equation of State

I. Brevik, E. Elizalde, O. Gorbunova +1

A dark Friedman-Robertson-Walker fluid governed by a non-linear inhomogeneous equation of state is considered which can be viewed as a conveniently simple paradigm for a whole clas…

Dark Energy Fluid with Time-Dependent, Inhomogeneous Equation of State

I. Brevik, O. G. Gorbunova, A. V. Timoshkin

The four-dimensional Friedman flat universe, filled with an ideal fluid with a linear (oscillating) inhomogeneous equation of state (EoS) depending on time, is studied. The equatio…

Variables separation in gravity

Valery V. Obukhov, Konstantin E. Osetrin

To solve the problem of exact integration of the field equations or equations of motion of matter in curved spacetimes one can use a class of Riemannian metrics for which the simpl…

Dilatonic Quantum-Induced Two-Brane Worlds

K. E. Osetrin

The 5d dilatonic gravity action with surface counterterms, motivated by the AdS/CFT correspondence and with contributions of brane quantum CFTs is considered with an AdS-like bulk.…
