Cosmological Perturbations in Quantum Cosmological Backgrounds |
We discuss the general properties of cosmological perturbations of quantum mechanical origin in quantum cosmological models with a bonce. We obtain a suiable nonsingular model were scalar and tensor perturbations have an almost scale invariant spectrum which is naturally led to the standard cosmological model evolution before nucleosynthesis. |
