摘要：

We discuss nonminimally coupled cosmologies including matter searching for exact solutions. As main result, we get that the quadratic coupling and the quartic potential for the scalar field phi, plus a dust-like matter imply a model starting with inflation, recovering Einstein gravity and ending up with a de Sitter stage, as requested by cosmic no-hair theorem. Furthermore, the today observed Newton constant can be interpreted as a remnant of SSB at GUT scales.
