Abstract

We consider the field equations for a flat FRW cosmological model, in a generic f(R)f(R) gravity model and cast them into a, completely normalized-dimensionless, system of O.D.Es for the scale factor and the function f(R)f(R), with respect to the scalar curvature RR. It is shown that under reasonable assumptions one can produce simple analytical and numerical solutions describing bouncing cosmological models where in addition there are late-time accelerating. Possibility of extending these results is briefly discussed.
