Entropy-corrected new agegraphic dark energy in Horava-Lifshitz cosmology

Abstract

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 Horava-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 ? ?(z)=? 0+? 1z, we obtain both ? 0 and ? 1. We find that in the presence of interaction, the equation of state parameter ? 0 of this model can cross the phantom divide line which is compatible with the observation. © 2012 Springer Science+Business Media B.V.
