New Cosmological Solutions in Nonlocal Modified Gravity

Abstract

We consider some cosmological aspects of nonlocal modified gravity with $\Lambda$ term, where nonlocality is of the type $R\mathcal{F}(\square )R$. Using ansatz of the form $\square R=rR+s,$ we find a few a(t) nonsingular bounce cosmological solutions for all three values of spatial curvature parameter k. We also discuss this modified gravity model from F(R) theory point of view.
