Bianchi type-II universe with linear equation of state

Abstract

Abstract:We have studied anisotropic and homogeneous Bianchi type-II cosmological model with linear equation of state (EoS) = αρ − β, where α and β are constants, in General Relativity. In order to obtain the solutions of the field equations we have assumed the geometrical restriction that expansion scalar θ is proportional to shear scalar σ . The geometrical and physical aspects of the model are also studied.PACS (2008)

Dark Energy Cosmological Models with Linear Equation of State in Plane Symmetric Universe

“…It is observed that, the fluid work as dark energy (negative pressure p ) depending on the particular values of α and β was shown in Figure 2 [12,14].…”

“…In this way, all possible expansion histories, the power law expansion, (12), and the exponential expansion, (13), have been covered.…”

“…al. [12][13][14][15] have studied cosmological models with equation of state normally relativity theory.…”
