Statefinder Diagnostic for Dilaton Dark Energy
Statefinder diagnostic is a useful method which can differ one dark energy model from the others. The Statefinder pair {r, s} is algebraically related to the equation of state of dark energy and its first time derivative. We apply in this paper this method to the dilaton dark energy model based on Weyl-Scaled induced gravitational theory. We investigate the effect of the coupling between matter...
متن کاملStatefinder diagnostic for holographic dark energy model
In this paper we study the holographic dark energy model proposed by Li from the statefinder viewpoint. We plot the evolutionary trajectories of the model with c = 1 in the statefinder parameter-planes. The statefinder diagrams characterize the properties of the holographic dark energy and show the discrimination between this scenario and other dark energy models. We also perform a statefinder ...
متن کاملStatefinder diagnostic for Yang-Mills dark energy model
We study the statefinder parameters in the Yang-Mills condensate dark energy models, and find that the evolving trajectories of these models are different from those of other dark energy models. We also define two eigenfunctions of the Yang-Mills condensate dark energy models. The values of these eigenfunctions are quite close to zero if the equation-of-state of the YangMills condensate is not ...
متن کاملStatefinder Parameters for Tachyon Dark Energy Model
In this paper we study the statefinder parameters for the tachyon dark energy model. There are two kinds of stable attractor solutions in this model. The statefinder diagrams characterize the properties of the tachyon dark energy model. Our results show that the evolving trajectories of the attractor solutions lie in the total region and pass through the LCDM fixed point, which is different fro...
متن کاملExploring dark energy using the Statefinder
Observations of high redshift supernovae indicate that the universe is accelerating. The hypothesis of ‘Dark energy’ (cosmological constant, scalar field tracker potentials, braneworld models, etc.) has been advanced to explain this phenomenon. Sensitive tests of dark energy which can differentiate between rival models are clearly the need of the hour. The statefinder pair {r, s} is a geometric...
