Some features of the radial gauge which are special of 2 + 1 dimensions are used to calculate classical solutions of Einstein's equations in 2 + 1 dimensions.
In addition to already known solutions we find new time independent and time dependent solutions both of point-like and extended nature.

We give a general procedure for extracting the propagators in gauge theories in the presence of a sharp galuge fixing and we apply it to derive the propagators in quantum gravity in the radial gauge, both in the first- and in the second-order formalism in any space-time dimension. In the threc-dimen
We develop the canonical ADM approach to 2+1 dimensional gravity in the presence of point particles. The instantaneous York gauge can be applied for open universes. The sequence of canonical ADM equations is solved in terms of the conformal factor. A simple derivation is given for the solution of th
The projector onto gauge invariant physical states was recently constructed for arbitrary constrained systems. This approach, which does not require gauge fixing nor any additional degrees of freedom beyond the original ones two characteristic features of all other available methods for quantising c
