Interacting Tsallis holographic dark energy: Cosmic behaviour, statefinder analysis and ${\omega }_D-{\omega }_D^{\prime }$ pair in the non-flat universe

Abstract

The paper explores the interacting Tsallis holographic dark energy (THDE) model in a non-flat universe following an infrared cutoff as the apparent horizon. The equation of state (EoS) and the deceleration parameter of THDE model are determined to understand the cosmological evolution for interacting THDE model in the nonflat universe. By applying the statefinder $(r,s)$ parameter-pairs diagnostic and ${\omega }_D-{\omega }_D^{\prime }$ pair dynamical analysis for the derived THDE model, we plot the evolutionary trajectories for different cases of Tsallis parameter $\delta$ and interaction term $b^2$ and also, for spatial curvature ${\Omega }_{k0}=0,-0.0012$ and $0.0026$ corresponding to flat, open and closed universes, respectively, in the framework of Planck 2018 base cosmology results VI-LCDM observational data.
