Interacting model of new agegraphic dark energy: Cosmological evolution and statefinder diagnostic

Cosmology and Nongalactic Astrophysics 2014-11-20 v2

Abstract

The statefinder diagnosic is a useful method for distinguishing different dark energy models. In this paper, we investigate the new agegraphic dark energy model with interaction between dark energy and matter component by using statefinder parameter pair {r,s}\{r, s\} and study its cosmological evolution. We plot the trajectories of the new agegraphic dark energy model for different interaction cases in the statefinder plane. As a result, the influence of the interaction on the evolution of the universe is shown in the statefinder diagrams.
