摘要：

A new class of dark energy model, known as "Tsallis agegraphic dark energy (TADE)," has been proposed using the holographic principle and Tsallis nonextensive entropy (Mod. Phys. Lett. A, 2019), considering the conformal time as well as the age of the Universe as IR cutoffs in flat Universe. The trajectories for evolution of statefinder parameters in (r, s), (r, q), (s, q) and the (omega(D), omega'(D)) planes are plotted for the TADE 1 and TADE 2 models for the value of the Tsallis parameter delta, and taking the TADE energy density parameter Omega(0)(D) = 0.70, according to the Planck 2018 results VI - Lambda CDM observational data without interaction.
