Axially Symmetric Dark Energy Cosmological Model In Scalar Tensor Theory of Gravitation

Abstract

Axially Symmetric Dark Energy model with variable equation of state (EoS) parameter is represented in the scalar tensor theory of Gravitation proposed by Saez and Ballester (Phys. Lett. A 113:467, 1986). To get a determinate solution of the field equation we take the help of special law of variation for Hubble parameter presented by Bermann which yields a cosmological model with negative constant deceleration parameter. Some physical and kinematical properties of model are also discussed. It is interesting to note that our results resemble with the results obtained by using , plane-symmetric space- time.
