Broglie interpretation of quantum mechanics is an alternative to
the Copenhaguen interpretation
which, as opposed to the last one, can be applied to a quantum theory of the Universe. In this approach, we
verified the existence of quantum cosmological models, free of singularities and horizons, which contract to a
non null minimum radius, and after expands as in the standard cosmological model for large values of the radius
as compared to the Planck length. We are investigating the evolution of quantum cosmological perturbations in
these scenarios and their consequences to the cosmic background radiation to see if the contracting epoch
preceding the expansion phase we live in can leed to observable facts.
Still in the quantum cosmological context, we are also studying quantum changes of topology.
General Relativity, we study generalizations of the definition of
gravitational energy to spaces which
are not asymptotically flat.
