I will present some exact cosmological solutions for modified gravity based on a nonlocal operator acting between two factors of the square root of R – 2 Lambda.

One of these solutions imitates properties similar to an interplay of the dark matter and the dark energy. For this solution, we computed some cosmological parameters which are in good agreement with observations. This talk is based on a recent paper published in Phys. Lett. B.
