Abstract
We perform Monte Carlo simulations of 2-d dynamically triangulated sur faces coupled to Ising and three-states Potts model matter. By measuri ng spin-spin correlation functions as a function of the geodesic dista nce we provide substantial evidence for a diverging correlation length at beta(c). The corresponding scaling exponents are directly related to the KPZ exponents of the matter fields as conjectured in [4].
