Query: Statefinder diagnostic and $w-w^{\prime}$ analysis for interacting
  polytropic gas dark energy model   The interacting polytropic gas dark energy model is investigated from the
viewpoint of statefinder diagnostic tool and $w-w^{\prime}$ analysis. The
dependency of the statefinder parameters on the parameter of the model as well
as the interaction parameter between dark matter and dark energy is calculated.
We show that different values of the parameters of model and different values
of interaction parameter result different evolutionary trajectories in $s-r$
and $w-w^{\prime}$ planes. The polytropic gas model of dark energy mimics the
standard $\Lambda$CDM model at the early time.
