Hamiltonian and Volume Operators
M. Pierri
Abstract
2+1 gravity coupled to a massless scalar field has an initial singularity when the spatial slices are compact. The quantized model is used here to investigate several issues of quantum gravity. The spectrum of the volume operator is studied at the initial singularity. The energy spectrum is obtained. Dynamics of the universe is also investigated.
