Cyclic, ekpyrotic and little rip universe in modified gravity
Shin'ichi Nojiri, Sergei D. Odintsov, Diego Saez-Gomez
We propose the reconstruction of gravity in such a way that corresponding theory admits cyclic and ekpyrotic universe solutions. The number of explicit examples of such $F(R…
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…
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…
Cosmological reconstruction of realistic modified F(R) gravities
Shin'ichi Nojiri, Sergei D. Odintsov, Diego Saez-Gomez
The cosmological reconstruction scheme for modified gravity is developed in terms of e-folding (or, redshift). It is demonstrated how any FRW cosmology may emerge from speci…
Modified f(R) gravity from scalar-tensor theory and inhomogeneous EoS dark energy
Diego Sáez-Gómez
The reconstruction of f(R)-gravity is showed by using an auxiliary scalar field in the context of cosmological evolution, this development provide a way of reconstruct the form of…
Oscillating Universe from inhomogeneous EoS and coupled dark energy
Diego Sáez-Gómez
An occurrence of an oscillating Universe is showed using an inhomogeneous equation of state for dark energy fluid. The Hubble parameter described presents a periodic behavior such…
