| contents | In this paper, we study the new Tsallis agegraghic dark energy model in the context of fractal cosmology. The different cosmic implications such as statefinder diagnosis, cosmological plane and squared of sound speed in both interacting and non-interacting scenarios are investigated. The study shows that the equation of state (EoS) parameter gives quintessence-like nature of Universe in both interacting and non-interacting cases. The results of the stability analysis for the distinct estimations of the nonadditive parameter $δ$ and coupling constant $b^2$ indicate that this model is unstable. Moreover, $ω_D-ω^{\prime}_{D}$ plane is in the freezing region in other words, cosmic expansion is more accelerating in the framework of fractal spacetime. |
