摘要
Recently, corrections of the type to Einstein-Hilbert action that become important at small curvature are proposed. Those type of models intend to explain the observed cosmic acceleration without dark energy. We derive the full Modified Friedmann equation in the Palatini formulation of those modified gravity model of the type. Then, we discuss various cosmological predictions of the Modified Friedmann equation.
