Euclidean and Lorentzian Quantum Gravity - Lessons from Two Dimensions
J. Ambjorn, J. L. Nielsen, J. Rolf +1
No theory of four-dimensional quantum gravity exists as yet. In this situation the two-dimensional theory, which can be analyzed by conventional field-theoretical methods, can serv…

The Spectral Dimension of 2D Quantum Gravity
J. Ambjorn, D. Boulatov, J. L. Nielsen +2
We show that the spectral dimension d_s of two-dimensional quantum gravity coupled to Gaussian fields is two for all values of the central charge c <= 1. The same arguments provide…
