Hamiltonian and Volume Operators
M. Pierri
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 qua…

Probing Quantum General Relativity Through Exactly Soluble Midi-Superspaces II: Polarized Gowdy Models
M. Pierri
Canonical quantization of the polarized Gowdy midi-superspace with a 3-torus spatial topology is carried out. As in an earlier work on the Einstein-Rosen cylindrical waves, symmetr…

Probing Quantum Gravity Through Exactly Soluble Midi-Superspaces I
A. Ashtekar, M. Pierri
It is well-known that the Einstein-Rosen solutions to the 3+1 dimensional vacuum Einstein's equations are in one to one correspondence with solutions of 2+1 dimensional general rel…
