    Abstract

    We present the results of a numerical simulation aimed at understanding the nature of the "c = 1 barrier" in two-dimensional quantum gravity. We study multiple Ising models living on dynamical phi3 graphs and analyse the behaviour of moments of the graph loop distribution. We note a universality at work as the average properties of typical graphs from the ensemble are determined only by the central charge. We further argue that the qualitative nature of these results can be understood from considering the effect of fluctuations about a mean field solution in the Ising sector.
