Crossing the Phantom Divide Line in a DGP-Inspired F(R,φ)-Gravity
Abstract
We study possible crossing of the phantom divide line in a DGP-inspired F(R,φ) braneworld scenario where scalar field and curvature quintessence are treated in a unified framework. With some specific form of F(R,φ) and by adopting a suitable ansatz, we show that there are appropriate regions of the parameters space which account for late-time acceleration and admit crossing of the phantom divide line.
