Extrinsic curvature as a reference fluid in canonical gravity
An introduction of embedding variables as physical fields locked to the metric by coordinate conditions helps to turn the quantum constraints into a many-fingered time Schroedinger equation. An attempt is made to generalize this process from noncanonical (Gaussian and harmonic) coordinate conditions...
