Abstract

A so-called "agegraphic dark energy" was recently proposed to explain the dark energy-dominated universe. In this Letter, we generalize the agegraphic dark energy models to the universe with spatial curvature in the presence of interaction between dark matter and dark energy. We show that these models can accommodate w_D = -1 crossing for the equation of state of dark energy. In the limiting case of a flat universe, i.e. k = 0, all previous results of agegraphic dark energy in flat universe are restored.
