Bouncing universes and their perturbations: remarks on a toy model

Abstract

Friedmann-Lemaitre universes driven by a scalar field, spatially closed and bouncing, were recently studied by Martin and Peter in [1], with the conclusion that the spectrum of their large scale matter perturbations was generically modified when going through the bounce. In this Note we give the properties of the scalar field potentials which underly such models.
