Loop Equation

We remark that the weak coupling regime of the stochastic stabilization of 2-D quantum gravity has a unique perturbative vacuum. By means of Monte-Carlo simulations we show that the nonperturbative vacuum has no bounded eigenvalues around the local minimum of the stabilized potential. Nonperturbative effects can be assessed in the loop equation. This can be derived from the Ward identities of the stabilized model and is shown to be modified by nonperturbative terms.

The equivalence of 2-dimensional quantum gravity and Liouville theory quantized with the standard translation invariant measure, is shown to hold to all orders in perturbation theory. Also, an explicit equation for the Liouville effective action as a function of the effective potential is derived from Weyl Ward identities. We speculate on some of the non-perturbative aspects of the theory.
