Statefinder parameters in two dark energy models
چکیده انگلیسی

The statefinder parameters (r,sr,s) in two dark energy models are studied. In the first, we discuss in four-dimensional General Relativity a two fluid model, in which dark energy and dark matter are allowed to interact with each other. In the second model, we consider the DGP brane model generalized by taking a possible energy exchange between the brane and the bulk into account. We determine the values of the statefinder parameters that correspond to the unique attractor of the system at hand. Furthermore, we produce plots in which we show s, r   as functions of red-shift, and the (s–rs–r) plane for each model.
