Description
Abstract: When quantizing a gravitational system that admits a suitable gauge-fixing of time by surfaces of constant-mean-curvature, the reduced phase space can be obtained non-perturbatively and, for pure gravity, it is realized as the cotangent bundle of the space of conformal geometries of the Cauchy slice. I will delineate how to apply this approach to quantize causal diamonds in (2+1)-dimensions, with a non-positive cosmological constant, employing a fully non-perturbative, group-theoretic quantization scheme based on a BMS_3 group of symmetries.
