Abstract

ABSTRACT We consider the flow equations for the three slow-roll parameters n[sub S] (scalar spectral index), r (tensor-to-scalar ratio), and dn[sub S]/d ln k (running of the spectral index). We show that the combination of these flow equations with the observational bounds from cosmic microwave background and large-scale structure allows one to put a lower bound on the fourth derivative of the inflationary potential, M[sup 4][sub P](Vā€³/V) > - 0.02 .
