    Papagiannopoulos, Giannis; Basilakos, Spyros; Barrow, John David; Paliathanasis, Andronikos (American Physical SocietyPhysical Review D - Particles, Fields, Gravitation and Cosmology, 2018-01-23)
    In the context of f(R)-gravity with a spatially flat FLRW metric containing an ideal fluid, we use the method of invariant transformations to specify families of models which are integrable. We find three families of f(R) ...
