摘要：

We perform Monte Carlo simulations using the Wolff cluster algorithm of multiple q = 2, 3, 4 state Potts models on dynamical phi-cubed graphs of spherical topology in order to investigate the c > 1 region of two-dimensional quantum gravity. Contrary to naive expectation we find no obvious signs of pathological behaviour for c > 1. We discuss the results in the light of suggestions that have been made for a modified DDK ansatz for c > 1.
