Bianchi Type V Dark Energy Model in Brans-Dicke Theory of Gravitation

S. D. Katore, A. Y. Shaikh

Abstract

Exact Bianchi type-V dark energy cosmological model with variable equation of state (E0S) parameter is obtained in a scalar-tensor theory of gravitation proposed by Brans and Dicke (Phys. Rev. 124:925, 1961). The scalar-tensor field equations have been solved by applying variation law for generalized Hubble’s parameter given by Bermann (Nuovo Cimento 74:182, 1983).Some physical and geometrical properties of the models are also discussed.
