Abstract
We construct a reparametrization invariant two-point function for c = -2 conformal matter coupled to two-dimensional quantum gravity. From t he two-point function we extract the critical indices nu and eta. The results support the quantum gravity version of Fisher's scaling relati on. Our approach is based on the transfer matrix formalism and exploit s the formulation of the c = -2 string as an O(n) model on a random la ttice. (C) 1997 Elsevier Science B.V.
