The unified history of the viscous accelerating universe and phase transitions
A. V. Astashenok, S. D. Odintsov, A. S. Tepliakov
We propose the unified description of the early acceleration (cosmological inflation) and the present epoch of so called "dark energy". The inflation can be described by cosmic flu…
Some models of holographic dark energy on the Randall-Sundrum brane and observational data
Artyom V. Astashenok, Alexander S. Tepliakov
The some models of holographic dark energy for Randall-Sandrum brane are considered. For first class of dark energy models we take energy density in form where …
