The emergence of background geometry from quantum fluctuations
arXiv:gr-qc/0607013 · doi:10.1016/j.physletb.2006.08.021
Abstract
We show how the quantization of two-dimensional gravity leads to an (Euclidean) quantum space-time where the average geometry is that of constant negative curvature and where the Hartle-Hawking boundary condition arises naturally.
