Abstract. We present an alternative procedure to eliminate irregular contributions in the perturbation expansion of $c\!\!=\!\!0$–matrix models representing the sum over triangulations of random surfaces, thereby reproducing the results of Tutte [1] and Brézin et al. [2] for the planar model. The advantage of this method is that the universality of the critical exponents can be proven from general features of the model alone without explicit determination of the free energy and therefore allows… Expand
