We investigate a class of shear-free and irrotational perfect fluid cosmological models in the context of modified (higher-order) gravitational theories. In particular, we generalize the potential and acceleration terms of the quasi-Newtonian formulation of General Relativity. We also show the existence of ``anti-Newtonian” cosmological models based on a consistency analysis of Einstein’s field equations applied to f(R)-gravity models.
