Bianchi Type-IX Anisotropic Dark Energy Cosmological Models with Time Dependent Deceleration Parameter

Abstract

Bianchi type-IX cosmological models with variable equation of state (EoS) parameter have been investigated in general relativity when universe is filled with dark energy. The field equations have been solved by considering (i) q B = (variable); (ii) q kt m 1 = − + − , where k and m are constants; (iii) 2 1 = − +. This renders early decelerating and late time accelerating cosmological models. The physical and geometrical properties of the models are also discussed.
