ABSTRACT

We study a model of F(R) gravity in which a crossing of the phantom divide can be realized. In particular, we demonstrate the behavior of F(R) gravity around a crossing of the phantom divide by taking into account the presence of cold dark matter.

Keywords:

Gravity, phantom divide expansion.
