The cosmological behavior and geometrical diagnostic for new Tsallis agegraphic dark energy with sign-changeable interaction

Abstract

We explore the cosmic behavior of the sign-changeable interacting new Tsallis agegraphic dark energy (NTADE) model in a spatially flat universe. The deceleration and the equation of state (EoS) parameters of the model are calculated. We also investigate the model in the universe with the spatial curvature. The spatial curvature may affect the time of onset of the acceleration. Furthermore, we demonstrate two geometric diagnostics analyses including the statefinder [Formula: see text] and [Formula: see text] to the discriminant the model from the standard LCDM model. The trajectories of evolution for [Formula: see text] and [Formula: see text] diagnostic planes are shown for different Tsallis parameter [Formula: see text] and interaction parameter [Formula: see text].
