NOTES ON THE (2+1)-DIMENSIONAL WHEELER-DEWITT EQUATION

In contrast to other approaches to (2 + 1)-dimensional quantum gravity, the Wheeler-DeWitt equation appears to be too complicated to solve explicitly, even for simple spacetime topologies. Nevertheless, it is possible to obtain a good deal of information about solutions and their interpretation. In particular, strong evidence is presented that Wheeler-DeWitt quantization is not equivalent to reduced phase space quantization.
