Description
I consider reconstruction of inflationary models in GR and f(R) gravity using information on the power spectrum of scalar perturbations only, ambiguity in this procedure and how it can be fixed by some aesthetic assumptions on the absence of new physical scales during and after inflation. Also discussed is the problem on the onset of inflation from generic classical curvature singularity preceding it, and which conditions are needed for this.
