摘要

In this paper,we study the evolution of a spatially flat universe composed of Tsallis agegraphic dark energy (TADE) and a pressureless dark matter (DM),by assuming that there is a signchangeable interaction between TADE and DM.The density,deceleration parameter and the equation of state parameters (EoS) show satisfactory behaviors in the model.By analysis we find that the accelerated expansion of the universe can be achieved at the late time if model parameters δ ＞ 2 and-2/3 ＜β ＜ 0.Also,we investigate the interacting TADE model by means of statefinder diagnostic and w-w'analysis.
