Show affiliationsRecently, corrections of the L(R) type to Einstein–Hilbert action that become important at small curvature have been proposed. These type of models are intended to explain the observed cosmic acceleration without dark energy. We derive the full modified Friedmann equation in the Palatini formulation of these modified gravity models of the L(R) type. Then, we discuss various cosmological predictions of the modified Friedmann equation.
