LRS Bianchi Type – II Model with Dark Matter and Holographic Dark Energy

Neelam Yadav

Abstract

In this paper we have investigated an anisotropic and spatially homogeneous LRS Bianchi type-II universe filled with minimally interacting dark matter and homographic dark energy. The exact solutions of the field equations are obtained by applying the hybrid expansion law for the average scale factor of the model. We have discussed physical and Kinematical properties of the model and the role of the anisotropic holographic dark energy in the evolution of the universe. The universe model is early decelerating and present time accelerating and the deceleration parameter has a signature flip at some finite time. We have observed that the anisotropy parameter of the universe and skewness parameter of the holographic dark energy approach to zero for large cosmic time and the universe can achieve flatness for some finite time throughout its evolution. The results are found to be consistent with the recent cosmological observations.

Keywords
