"Quantum Gravity and Hamilton-Jacobi theory"
(Universidad de Santiago de Chile)
Abstract: Following analogies with relativistic point particles, and
Schild strings, we show that the Einstein gravity and its strong
coupling regime (or the Planck mass going to 0) are related to each
other through a Laplace transform. The Feynman propagator of gravity
in the strong coupling regime satisfies a functional diffusion
equation in the three-metric space with the evolution parameter being
the volume of spacetime. We conjecture that the relationship between
both regimes is consistent with the existence of an evolution operator
in which time is replaced by the volume of spacetime.
