摘要
In this article in a generalization of our previous work (Farajollahi and Milani in Mod. Phys. Lett. A 25:2349–2362, 2010), we investigate the dynamics of the non-local F(R) gravity after casting it into local form. The non-singular bouncing behavior and quintom model of dark energy are achieved without involving negative kinetic energy fields. Two cosmological tests are performed to constrain the model parameters. In case of phantom crossing the distance modulus predicted by the model best-fits the observational data. In comparison with the CPL parametrization for drift velocity, the model in some redshift intervals is in good agreement with the data.
