Five-dimensional FRW Modified Holographic Ricci Dark Energy Cosmological Models with Hybrid Expansion Law in a Scalar-Tensor Theory of Gravitation

In this paper, we consider a five dimensional FRW space-time filled with dark matter and modified holographic Ricci dark energy in a scalar-tensor theory of gravitation. To solve the field equations of the theory we have used hybrid expansion law which shows a transition from decelerated phase to an accelerated phase in a scalar-tensor cosmology. The EoS parameter, jerk parameter and average density parameter are determined. We have also studied the physical and geometrical properties of the model.
