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.
