Abstract

An intermediate inflationary Universe model in the context of non-minimal coupling to the scalar curvature is analyzed. We will conduct our analysis in the slow-roll approximation of the inflationary dynamics and the cosmological perturbations considering a coupling of the form F(φ) = κ+ ξ n φ n . Considering the trajectories in the r–n s plane from the Planck data, we find the constraints on the parameter space in our model.
