Covariance of the algebra of constraints of 4-D general relativity
arXiv:0901.3041
Abstract
We argue that the standard canonical treatment of GR breaks manifest spacetime covariance. We present new variables which carry a reducible representation of gauge transformations and spacetime diffeomorphisms. A proposal is presented for an action designed to realize these symmetries at the canonical level.
