Reconstructing f(R) modified gravity from ordinary and entropy-corrected versions of the holographic and new agegraphic dark energy models
Here, we peruse cosmological usage of the most promising candidates of dark energy in the framework of f ( R ) theory. We reconstruct the different f ( R ) modified gravity models in the spatially flat FRW universe according to the ordinary and entropy-corrected versions of the holographic and new a...

Zusammenfassung: | Here, we peruse cosmological usage of the most promising candidates of dark energy in the framework of
f
(
R
) theory. We reconstruct the different
f
(
R
) modified gravity models in the spatially flat FRW universe according to the ordinary and entropy-corrected versions of the holographic and new agegraphic dark energy models, which describe accelerated expansion of the universe. We also obtain the equation of state parameter of the corresponding
f
(
R
)-gravity models. We conclude that the holographic and new agegraphic
f
(
R
)-gravity models can behave like phantom or quintessence models. Whereas the equation of state parameter of the entropy-corrected models can transit from quintessence state to phantom regime as indicated by recent observations. |
