Scalar-tensor cosmology with R^{-1} curvature correction by Noether Symmetry

arXiv:0807.0347 · doi:10.1016/j.physletb.2008.06.058

Abstract

We discuss scalar-tensor cosmology with an extra $R^{-1}$ correction by the Noether Symmetry Approach. The existence of such a symmetry selects the forms of the coupling $ω(ϕ)$, of the potential $V(ϕ)$ and allows to obtain physically interesting exact cosmological solutions.
