 Planckian hypersurfaces, inflation and bounces / Giovannini, Massimo (CERN ; INFN, Milan Bicocca) When the different wavelengths of the scalar and tensor modes of the geometry are all assigned on the same space-like hypersurface the maximally amplified frequencies of the spectrum remain smaller than the Planck mass only if the duration of a stage of accelerated expansion and the corresponding tensor to scalar ratio are severely constrained.
