摘要：
We discuss scalar-tensor cosmology with an extra R-I correction by the Noether symmetry approach. The existence of such a symmetry selects the forms of the coupling omega(phi), of the potential V(phi) and allows to obtain physically interesting exact cosmological solutions. (c) 2008 Elsevier B.V.
