Five dimensional minimally interacting holographic dark energy model in Brans–Dicke theory of gravitation

Abstract

In this paper, we investigate five dimensional space–time filled with minimally interacting dark matter and holographic dark energy in Brans–Dicke (Phys. Rev. 124:925, 1961) scalar–tensor theory of gravitation. The exact solutions of the field equations are obtained using (i) special law of variation for Hubble’s parameter that yields constant value of deceleration parameter and (ii) a relation between metric potentials. The physical and geometrical aspects of the model are also discussed.
