摘要
A qualitative analysis of a scalar-tensor cosmological model, with an exponential potential for the scalar field, is performed. The phase diagram for the flat case is constructed. It is shown that solutions with an initial and final inflationary behavior appear. We discuss the possible existence of realistic scenarios and we generalize the results, adding ordinary matter to the scalax-tensor model.
