The Conformal Constraint in Canonical Quantum Gravity
Gerard 't Hooft
Perturbative canonical quantum gravity is considered, when coupled to a renormalizable model for matter fields. It is proposed that the functional integral over the dilaton field s…

Probing the small distance structure of canonical quantum gravity using the conformal group
Gerard 't Hooft
In canonical quantum gravity, the formal functional integral includes an integration over the local conformal factor, and we propose to perform the functional integral over this fa…
