Agegraphic dark energy with the sign-changeable interaction in non-flat universe

In this paper, we investigate the agegraphic dark energy (ADE) model by including the sign-changeable interaction between ADE and dark matter in non-flat universe. It is shown that the interaction induces an energy flow of which the direction is first from dark matter to ADE and then from ADE to dark matter. The phase space analysis is made and the critical points are found, one of which is the accelerated scaling attractor solution. So, the coincidence problem can be alleviated. Furthermore, we show the evolution of the density parameter $\Omega$, the deceleration parameter $q$ and the equation of state (EoS) parameter $w_{d}$ of ADE. We also find that our model is consistent with the observational data.
