On the CDM Universe in gravity
Ratbay Myrzakulov, Diego Sáez-Gómez, Anca Tureanu
In the context of the so-called Gauss-Bonnet gravity, where the gravitational action includes function of the Gauss-Bonnet invariant, we study cosmological solutions, especially th…
Unifying inflation with dark energy in modified F(R) Horava-Lifshitz gravity
E. Elizalde, S. Nojiri, S. D. Odintsov +1
We study FRW cosmology for a non-linear modified F(R) Horava-Lifshitz gravity which has a viable convenient counterpart. A unified description of early-time inflation and late-time…
On the LCDM Universe in f(R) gravity
Peter K. S. Dunsby, Emilio Elizalde, Rituparno Goswami +2
Several different explicit reconstructions of f(R) gravity are obtained from the background FRW expansion history. It is shown that the only theory whose Lagrangian is a simple fun…
Cardy-Verlinde formula in FRW Universe with inhomogeneous generalized fluid and dynamical entropy bounds near the future singularity
Iver Brevik, Shin'ichi Nojiri, Sergei D. Odintsov +1
We derive a Cardy-Verlinde-like formula which relates the entropy of the closed FRW universe to its energy, and Casimir energy, for a multicomponent coupled fluid. The generalized…
LambdaCDM epoch reconstruction from F(R,G) and modified Gauss-Bonnet gravities
Emilio Elizalde, Ratbay Myrzakulov, Valery V. Obukhov +1
Dark energy cosmology is considered in a modified Gauss-Bonnet model of gravity with and without a scalar field. It is shown that these generalizations of General Relativity endow…
