Dynamics of Viscous Phantom Universe
  The phantom dark energy remarkably boosts our prehension of the accelerating
Universe. Various models are widely discussed in the phantom Universe without
bulk viscosity. From the hydrodynamics' point of view, it is natural to
introduce the nonperfect fluid in the study of the Universe, as an ideal fluid
just an approximation to the real world after all and using the generalized
equation of state (EoS) with bulk viscosity, the early inflationary universe
and the accelerated expansion of the late-time universe are described by many
authors. In this paper, in order to investigate how the viscosity will
influence the evolution of the Universe, we study a class of phantom dark
energy models with bulk viscosity by the method of dynamical analysis
technique. We show that there are different cosmic late-time behaviors and the
stability also brings some constraints on the models. We also plot the
evolutionary trajectories of this model in the statefinder parameter-planes to
see the different behaviors of the models from the statefinder viewpoint.
