| Popis: | We investigate the new Tsallis agegraphic dark energy (NTADE) scenario in the framework of Horava-Lifshitz cosmology. Considering interacting and non-interacting scenarios of NTADE with dark matter in a spatially non-flat universe, we investigate the cosmological implications of this model in detail. We obtain the differential equation of the evolution of the density parameter, the equation of state parameter and the classical stability of model. Also, we study the behavior of the deceleration parameter and investigate the nature of the statefinder diagnostics and $\omega_D-{\omega_D}^{\prime}$ plane. We find that phantom crossing cannot occur for the state parameter in this scenario and from the plot of the deceleration parameter, we have observed a transition from decelerating to accelerating phase of the univese. Also, the sign of the square of the sound speed is negative which means unstable behavior at this scenario. The $\omega_D$ and ${\omega_D}^{\prime}$ have negative values which represents the freezing region at here. Comment: 10 pages, 21 figures |
