A dark energy model interacting with dark matter and unparticle

We study dynamical behaviors of dark energy models interacting with dark matter and unparticle in the standard flat Friedmann-Robertson-Walker cosmology. We considered four different interacting models and examined the stability of the critical points. We find that there exist late-time scaling attractors corresponding to an accelerating universe, and the alleviation of the coincidence problem depends on the choice of parameters in the models.
