We discuss a model of gravity coupled to a scalar field that admits exact cosmological solutions displaying an inflationary behavior at early times and a power-law expansion at late times. We study its general solutions and the effect of the inclusion of matter.

Abstract
We discuss a model of gravity coupled to a scalar field that admits exact cosmological solutions displaying an inflationary behavior at early times and a power-law expansion at late times. We study its general solutions and the effect of the inclusion of matter.
