S.Dalley, C.Johnson, T.Morris
TL;DR
This paper reviews recent developments in non-perturbative 2D quantum gravity coupled to matter with central charge less than one, utilizing flows of the generalized KdV hierarchy to establish stability.
Contribution
It introduces a non-perturbative approach to 2D quantum gravity using KdV hierarchy flows, providing a stable framework for c<1 matter coupling.
Findings
Demonstrates non-perturbative stability of 2D quantum gravity models
Connects KdV hierarchy flows with quantum gravity dynamics
Updates previous models with new stability insights
Abstract
This is a talk given by S.D. at the the workshop on Random Surfaces and 2D Quantum Gravity, Barcelona 10-14 June 1991. It is an updated review of recent work done by the authors on a proposal for non-perturbatively stable 2D quantum gravity coupled to c<1 matter, based on the flows of the (generalised) KdV hierarchy.
