Kaluza-Klein Minimally Interacting Holographic Dark Energy Model Using Linearly Varying Deceleration Parameter in Brans-Dicke Theory of Gravitation

D. R. K. Reddy, S. Anitha, S. Umadevi


In this paper, we investigate five dimensional Kaluza-Klein universe 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) linearly varying deceleration parameter proposed by Akarsu and Dereli (Int. J. Theor. Phys. 51: 612, 2012); and (ii) a relation between metric potentials. The physical and geometrical aspects of the model are also discussed.
