Gauss-Bonnet Braneworld Cosmology with Modified Induced Gravity on the Brane

[摘要] We analyze the background cosmology for an extension of the DGP gravity with Gauss-Bonnet term in the bulk and f(R) gravity on the brane. We investigate implications of this setup on the late-time cosmic history. Within a dynamical system approach, we study cosmological dynamics of this setup focusing on the role played by curvature effects. Finally, we constrain the parameters of the model by confrontation with recent observational data.
