Nettet15. aug. 2008 · We consider an interacting holographic dark energy model in Friedmann-Robertson-Walker spacetime with positive spatial curvature and investigate the behavior of the geometric parameter and dark energy density in an accelerated expanding epoch. We also derive some conditions needed to cross the phantom dividing line in this model. … NettetWe investigate the QCD ghost model of dark energy in the framework of Brans–Dicke cosmology. First, we study the non-interacting ghost dark energy in a flat Brans–Dicke theory. In this case we obtain the equation of state and the deceleration parameters and a differential equation governing the evolution of ghost energy density. Interestingly …
