摘要：

The general formalism for stabilizing bottomless euclidean field theories (the "fifth time" action) provides a natural non-perturbative definition of matrix models corresponding to 2D quantum gravity. The formalism allows, in principle, the use of lattice Monte Carlo techniques for non-perturbative computation of correlation functions. © 1990.
