An interacting two-fluid scenario for dark energy in a Bianchi type-I cosmological model

Triloki Singh, Raghavendr Chaubey

Abstract

We study the evolution of the dark energy parameter within a Bianchi type-I cosmological model filled with barotropic fluid and dark energy. The solutions have been obtained for power law and exponential forms of the expansion parameter (they correspond to a constant deceleration parameter in general relativity). After a long time, the models tend to be isotropic under certain conditions.

Keywords


cosmological model — dark energy parameter — barotropic fluid
