摘要：

We present a class of scalar-tensor gravity theories which admit simple Friedmann cosmological models in the vacuum and radiation-dominated cases. A subclass of these theories yields a one-parameter family of cosmological models displaying either expansion from an initial singularity or a bounce following contraction from an infinite extended initial state.
