The Cosmological Models with Jump Discontinuities
Artyom V. Yurov, Artyom V. Astashenok, Valerian A. Yurov
The article is dedicated to one of the most undeservedly overlooked properties of the cosmological models: the behaviour at, near and due to a jump discontinuity. It is most intere…
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…
The cosmological constant as an eigenvalue of a Sturm-Liouville problem
Artyom V. Yurov, Artyom V. Astashenok, E. Elizalde
It is observed that one of Einstein-Friedmann's equations has formally the aspect of a Sturm-Liouville problem, and that the cosmological constant, , plays thereby the role of s…
An Infrared Divergence Problem in the cosmological measure theory and the anthropic reasoning
Artyom V. Yurov, Valerian A. Yurov, Artyom V. Astashenok +1
An anthropic principle has made it possible to answer the difficult question of why the observable value of cosmological constant ( GeV) is so disconcertingly…
Brane-like singularities with no brane
A. V. Yurov
We use a method of linearization to study the emergence of the future cosmological singularity characterized by finite value of the cosmological radius. We uncover such singulariti…
