Abstract

We have studied anisotropic and homogeneous Bianchi type-VIh cosmological models of the universe with variable equation of state (EoS) parameter (w) in General Relativity. A special form of deceleration parameter (q) which gives an early deceleration and late time accelerating cosmological model has been utilized to solve the Einstein's field equations. The geometrical and physical aspects of the models are also studied.

Keywords

Abstract

Vacuum field equations for the Einstein-Rosen cylindrically symmetric metric are obtained in a scalar-tensor theory of gravitation proposed by Ross [D.K. Ross, Phys. Rev. D. 5 (1972), 284]. It is shown that in each of the static and non-static cases the solutions of the field equations simply yield the vacuum models of general relativity.

Keywords
