We extend the concept of quintessence to flat nonminimally coupled scalar– 1 tensor theories of gravity. By means of Noether’s symmetries for the cosmological pointlike Lagrangian L, it is possible to exhibit exact solutions for a class of models depending on a free parameter s. This parameter comes out in the relationship existing between the coupling F… (More)
