چکیده مقاله:

Purpose of this paper is to study generalizedquantum chromodynamics ghost dark energy (GDE) in theframe work of Horava–Lifshitz cosmology. Consideringinteracting and non-interacting scenario of GDE with darkmatter in a spatially non-flat universe, we investigate thecosmological implications of this model in detail. Weobtain equation of state parameter, deceleration parameterand the evolution of dark energy density to explain theexpansion of the universe. Also, we show that the resultswe calculate have a good compatibility with previous workand restore it in limiting case. Further, we investigatevalidity of generalized second law of thermodynamics inthis scenario. Finally, we find out a cosmological applicationof our work by evaluating a relation for the equation ofstate of dark energy for law redshifts.
