Scientific paper

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.
