Title: The fractal structure of two-dimensional quantum gravity.

Abstract: The path integral of two-dimensional quantum gravity can be analyzed using the formalism of dynamical triangulations. It can be shown that the quantum spacetime is fractal, the fractal dimension being a function of the central charge of the conformal field theory coupled to the two-dimensional geometry.
