Cosmology from anisotropic DGP braneworld

Abstract

We considered an anisotropic brane embedded in a five-dimensional bulk space-time. The Einstein equations and Friedmann equations are obtained. The corresponding Friedmann equations are modified with quadratic corrections to energy density. The anisotropic DGP model also admits a self-accelerating phase in the late universe. The acceleration conditions are obtained and they are consistent with the braneworld scenario. The acceleration condition for DGP model, in the late universe, is dependent on the crossover scale rc. © 2010 World Scientific Publishing Company.
