New exact cosmologies on the brane
Artyom V. Astashenok, Artyom V. Yurov, Sergey V. Chervon +2
We develop a method for constructing exact cosmological solutions in brane world cosmology. New classes of cosmological solutions on Randall-Sandrum brane are obtained. The superpo…
The possible resolution of Boltzmann brains problem in phantom cosmology
Artyom V. Astashenok, Artyom V. Yurov, Valerian V. Yurov
We consider the well-known Boltzmann brains problem in frames of simple phantom energy models with little rip and big rip singularity. It is showed that these models (i) satisfy to…
Application of the Abel Equation of the 1st kind to an inflation analysis of non-exactly solvable cosmological models
Anna V. Yaparova, Artyom V. Yurov, Valerian A. Yurov
In this paper we revisit the relationship between the Einstein--Friedman and the Abel equations to demonstrate how it might be applied to the inflationary analysis in a flat Friedm…
Brane cosmology from observational surveys and its comparison with standard FRW cosmology
A. V. Astashenok, E. Elizalde, J. de Haro +2
Several dark energy models on the brane are investigated. They are compared with corresponding theories in the frame of 4d Friedmann-Robertson-Walker cosmology. To constrain the pa…
