Dirac observables and boundary proposals in quantum cosmology
arXiv:1403.2424 · doi:10.1103/PhysRevD.89.083504
Abstract
We study the reduced phase space quantization of a closed Friedmann Universe, where matter content is constituted by two (no-interacting) fluids, namely dust (or cold dark matter) and radiation. It is shown that, for this particular model, specific boundary conditions can be related to the algebra of Dirac observables.
