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.

โฆ Synopsis
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-dimensional case such propagators vanish except for singular collinear contributions, in agreement with the absence of propagating gravitons. I 199.3 Academic Press. Inc

In the functional integral formalism of quantum field theory a gauge breaking term is added to the classical action in order to parametrize the orbits of the gauge group. I n quantum gravity this gauge breakjng term fixes the orientation of the Riemannian metric with respect to a fixed reference met
