摘要：

In the framework of f (R) scalar-tensor cosmology, we use the Noether symmetry approach to find the cosmological models consistent with the Noether symmetry. We obtain the functions f (R) and H (a), or the corresponding differential equations, according to specific choices for the scalar field potential V (phi), the Brans-Dicke function omega(phi), some cosmological parameters, and the constants of motion. This enables us to choose the viable scalar-tensor cosmologies from the Noether symmetry point of view.
