| Popis: | Proceedings of the Thirteenth Marcel Grossman Meeting on General Relativity, Singapore, 2015 We completely quantize the model consisting of scalar perturbations around a homogeneous and isotropic universe filled with a massive scalar field and with positive-curvature spatial sections. A gauge fixing is performed so as to remove the spurious local degrees of freedom. The homogeneous sector is then quantized with loop techniques, while the inhomogeneities are described by a standard Fock representation which is uniquely determined by the symmetries of the spatial sections and the requirement of unitary dynamics. We provide a quantum Hamiltonian constraint and characterize its solutions in terms of their initial value on the minimum volume section. An equivalent formulation in terms of gauge invariants is commented. |
