MULTICRITICALITY IN STABILIZED 2D QUANTUM GRAVITY
Modern Physics Letters A, 1992We study the simplest perturbation of the matrix model for pure gravity susceptible of reaching the k=3 multicritical point in the framework of the stochastic stabilization of 2D quantum gravity. We show the existence of a line of points in the phase diagram with the genuine critical behavior of the k=2 theory.

FIRST ORDER, 2D, EINSTEIN GRAVITIES
International Journal of Modern Physics D, 1996The Palatini variational method breaks down in 2D: First order forms of the Einstein action do not fix the affinity completely, as they possess an additional, Weyl, invariance absent in the second order versions.

The physical subspace of the SL (2, R) current algebra based model of induced 2d gravity is investigated. Using an appropriate ground state, an equation guaranteeing the non-negativity of this subspace is derived using a BRS analysis. In case of the ground state allowing the derivation of simple differential equations for the correlation functions the

To any finite order in perturbation theory, one does not see any of the interesting nonperturbative properties of gauge theories, such as confinement, tunneling, formation of strings, etc. As a consequence, two approximations have been developed, large N methods and lattice gauge theory, to analyze gauge theories in the nonperturbative regime. However,
