Non-flat universe and interacting dark energy model

For non-flat universe of k≠0, we investigate a model of the interacting holographic dark energy with cold dark matter (CDM). There exists a mixture of two components arisen from decaying of the holographic dark energy into CDM. In this case we use the effective equations of state (ωΛeff,ωmeff) instead of the native equations of state (ωΛ,ωm). Consequently, we show that interacting holographic energy models in non-flat universe cannot accommodate a transition from the dark energy to the phantom regime.
