Interactingdark energy and the holographic principle offer a possible wayof addressing the cosmic coincidence problem as well as accountingfor the size of the dark energy component. The equilibriumpoints of the Friedmann equations which govern the evolution behaviorof dark energy, matter, and curvature components can determine thequalitative behavior of the cosmological models. These possible equilibria andtheir behavior are examined in a general framework, and someillustrative examples are presented.
