From Big to Little Rip in modified F(R,G) gravity (1201.4742v2)
Published 23 Jan 2012 in gr-qc
Abstract: We discuss the cosmological reconstruction in modified Gauss-Bonnet (GB) gravity. It is demonstrated that the modified GB gravity may describe the most interesting features of late-time cosmology. We derive explicit form of effective phantom cosmological models ending by the finite-time future singularity (Big Rip) and without singularities in the future (Little Rip).
