Abstract
We establish a connection between the agegraphic models of dark energy and Chaplygin gas energy density in a nonflat universe. We reconstruct the potential of the agegraphic scalar field as well as the dynamics of the scalar field according to the evolution of the agegraphic dark energy. We also extend our study to the interacting agegraphic generalized Chaplygin gas dark energy model.
Highlights
Over the course of the past decade, evidence for the most striking result in modern cosmology has been steadily growing, namely the existence of an exotic dark energy component which has negative pressure and pushes the universe to accelerated expansion [1]
We suggest the agegraphic description of the Chaplygin gas dark energy in FRW universe and reconstruct the potential and the dynamics of the scalar field which describe the Chaplygin cosmology
In this Letter, we have established a correspondence between the agegraphic dark energy scenarios and the Chaplygin gas model of dark energy in non-flat FRW cosmology
Summary
Over the course of the past decade, evidence for the most striking result in modern cosmology has been steadily growing, namely the existence of an exotic dark energy component which has negative pressure and pushes the universe to accelerated expansion [1]. The holographic and agegraphic dark energy models possess some significant features of quantum gravity The former, that arose a lot of enthusiasm recently [3,4,5,6,7,8,9], is motivated from the holographic hypothesis [10] and has been tested and constrained by various astronomical observations [11]. Where ρD > 0 and pD are, respectively, the energy density and pressure of Chaplygin gas dark energy, and A is a positive constant This equation of state has raised a certain interest [21] because of its many interesting and, in some sense, intriguingly unique features.
