Bianchi Type-IX Minimally Interacting Holographic Dark Energy Model with Linearly Varying Deceleration Parameter in Scalar-tensor Theory of Gravitation
Abstract
In this paper, we investigate spatially homogeneous and anisotropic Bianchi type-IX space-time filled with two minimally interacting fields, matter and holographic dark energy components in the scalar-tensor theory of gravitation formulated by Saez and Ballester (1986).To obtain exact solution of the field equations we have used: (i) The fact that scalar expansion is proportional to shear scalar of the space-time; and (ii) Linearly varying deceleration parameter proposed by Akarsu and Dereli (I2012). Some physical and kinematical properties of the model are, also, discussed.
