Dark Energy Model with Non-Minimal Coupling and Cosmological Constant Boundary

Dark Energy Model with Non-Minimal Coupling and Cosmological Constant Boundary

In this paper, we study a kind of dark energy models in the framework of the non-minimal coupling. With this kind of models, dark energy could cross the cosmological constant boundary, and at early time, dark energy could have ＂tracking＂ behavior.
