Abstract
Non-minimally coupled theories of special potentials are analyzed numerically. Such theories yield equations of state Ï<â1 and oscillations of the cosmological expansion, which are favored by the recent analysis of observations. Fitting these theories to the Gold SnIa dataset, we obtain results comparable with other models. A potential of the form V(Ï)=V0ea1Ï2 yields Ïmin2=170.127. Similar results are obtained for potentials of the form V(Ï)=V0+a1Ïn.
