Statefinder Diagnostic for Phantom Model with V(

We investigate the phantom field with potential V(Ф)=V₀(-λФ²) and dark matter in the spatially flat Friedman--Robertson--Walker model. It has been shown by numerical calculation that there is a attractor solution in this model. We also apply the statefinder diagnostic to this phantom model. It is shown that the evolving trajectories of this scenario in the s-r diagram is quite
different from other dark energy models.
