چکیده
We study the entropy-corrected version of the new agegraphic dark energy (NADE) model and dark matter in a spatially non-flat Universe and in the framework of Hoˇrava-Lifshitz cosmology. For the two cases containing noninteracting and interacting entropy-corrected NADE (ECNADE) models, we derive the exact differential equation that determines the evolution of the ECNADE density parameter. Also the deceleration parameter is obtained. Furthermore, using a parametrization of the equation of state parameter of the ECNADE model as ω(z) = ω0 +ω1z, we obtain both ω0 and ω1. We find that in the presence of interaction, the equation of state parameter ω0 of this model can cross the phantom divide line which is compatible with the observation.
