Léon Rosenfeld's general theory of constrained Hamiltonian dynamics
Donald Salisbury, Kurt Sundermeyer
This commentary reflects on the 1930 discoveries of Léon Rosenfeld in the domain of phase-space constraints. We start with a short biography of Rosenfeld and his motivation for thi…

Restoration of four-dimensional diffeomorphism covariance in canonical general relativity: An intrinsic Hamilton-Jacobi approach
Donald Salisbury, Jürgen Renn, Kurt Sundermeyer
Classical background independence is reflected in Lagrangian general relativity through covariance under the full diffeomorphism group. We show how this independence can be maintai…

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…
