On the Universality of Nonperturbative effects in Stabilized 2D Quantum Gravity

Abstract

In this letter I study the universality of the nonperturbative effects and the vacua structure of the stochastic stabilization of the matrix models which defines Pure 2D Quantum Gravity. I show also that there is not tunneling, in the continuum limit, between the one-arc and three-arc solutions of the simplest matrix model which defines the flow between Pure Gravity and the Lee-Yang model.
