Revisiting observables in generally covariant theories in the light of gauge fixing methods

J. M. Pons, D. C. Salisbury, K. A. Sundermeyer

We derive for generally covariant theories the generic dependency of observables on the original fields, corresponding to coordinate-dependent gauge fixings. This gauge choice is e…
