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.
