• BIANCHI TYPE-VI0 DARK ENERGY MODEL WITH VARIABLE EoS PARAMETER IN A SAEZ-BALLESTER SCALAR-TENSOR THEORY OF GRAVITATION

Md. Azizur Rahman*, M. Ansari#

Abstract


Bianchi Type-VI0 cosmological model is investigated in a Saez-Ballester scalar-tensor theory of gravitation. Three different time-dependent skewness parameters along spatial directions are introduced to represent the deviation of pressure from isotropy. Exact solutions of the field equations are obtained by assuming a special law of variation for the mean Hubble’s parameter, which yields a constant value of deceleration parameter. Some physical and geometrical properties of the model are discussed.


Keywords


Bianchi type-VI0 model, Dark energy, Scalar-tensor theory.
