On energy-momentum tensor for gravitational waves in gravity
Petr V. Tretyakov, Alexander N. Petrov
The classical Isaacson's procedure for describing back-reaction of the averaged energy-momentum for high frequency gravitational waves is generalized to the gravity case. Fr…
Spin connection and cosmological perturbations in scalar-torsion gravity
Alexey V. Toporensky, Petr V. Tretyakov
In this paper we generalize our previous results on spin connection for the linear scalar cosmological perturbation in theory to wider class of theories which includes a sca…
Bianchi I cosmological solutions in teleparallel gravity
Petr V. Tretyakov
In the present paper we discuss dynamic of anisotropic Bianchi I Universe filled by the perfect fluid in teleparallel -gravity. By using as analytical as numerical approaches…
Spin connection and cosmological perturbations in gravity
A. Toporensky, P. Tretyakov
In this paper we study cosmological perturbations in teleparallel gravity. We discuss problems which appear in standard approach to gravity, and find that these problems may…
Cosmology in modified -gravity
Petr V. Tretyakov
In present paper we propose further modification of -gravity (where is trace of energy-momentum tensor) by introducing higher derivatives matter fields. We discuss stab…
Phase Space Analysis of the Accelerating Multi-fluid Universe
S. D. Odintsov, V. K. Oikonomou, Petr V. Tretyakov
We study in detail the phase space of a Friedmann-Robertson-Walker Universe filled with various cosmological fluids which may or may not interact. We use various expressions for th…
