The two-point function of c = −2 matter coupled to 2D quantum gravity Original Research Article

We construct a reparametrization invariant two-point function for c = −2 conformal matter coupled to two-dimensional quantum gravity. From the two-point function we extract the critical indices ν and η. The results support the quantum gravity version of Fissherʹs scaling relation. Our approach is based on the transfer matrix formalism and exploits the formulation of the c = −2 string as an O(n) model on a random lattice.
