Modified holographic Ricci dark energy model and statefinder diagnosis
  in flat universe
  Evolution of the universe with modified holographic Ricci dark energy model
is considered. Dependency of the equation of state parameter and deceleration
parameter on the redshift and model parameters are obtained. It is shown that
the density evolution of both non-relativistic matter and dark energy are the
same until recent times. The evolutionary trajectories of the model for
different model parameters are obtained in the statefinder planes, r-s and r-q
planes. The present statefinder parameters are obtained for different model
parameter values, using that the model is differentiated from other standard
models like $\Lambda$CDM model etc. We have also shown that the evolutionary
trajectories are depending on the model parameters, and at past times the dark
energy is behaving like cold dark matter, with equation of state equal to zero.
