Dynamical Evolution of Interacting Modified Chaplygin Gas

Understand

The cosmological model of the modified Chaplygin gas interacting with cold dark matter is studied.

• Our attention is focused on the final state of universe in the model.
• It turns out that there exists a stable scaling solution, which provides the possibility to alleviate the coincidence problem.
• In addition, we investigate the effect of the coupling constants $c_{1}$ and $c_{2}$ on the dynamical evolution of this model from the statefinder viewpoint.
