Holographic Dark Energy Model with Generalized Chaplygin Gas in a Scalar-tensor Theory of Gravitation

V. M. Santhi, V. U. M. Rao, Y. Aditya


The present work deals with a five dimensional spherically symmetric space-time filled with two minimally interacting fluids: matter and holographic dark energy in SaezBallester [1] scalar tensor theory of gravitation. We have investigated geometric and kinematic properties of the model and the role of the holographic dark energy in the evolution of the spherically symmetric universe. We established a correspondence between the holographic dark energy model with the generalised Chaplygin gas dark energy model. We also reconstructed the potential and dynamics of the scalar field which describes the Chaplygin cosmology.
