Unitary Matrix Models and 2D Quantum Gravity (Virasoro constraints modified)
S. Dalley, C. V. Johnson, T. R. Morris +1
The KdV and modified KdV integrable hierarchies are shown to be different descriptions of the same 2D gravitational system -- open-closed string theory. Non-perturbative solutions…
The Boundary Cosmological Constant in Stable 2D Quantum Gravity
Clifford V. Johnson, Tim R. Morris, Peter L. White
We study further the rôle of the boundary operator for macroscopic loop length in the stable definition of 2D quantum gravity provided by the formulation.…
Global KdV Flows and Stable 2D Quantum Gravity
Clifford V. Johnson, Tim R. Morris, Anders Wätterstam
The string equation for the formulation of non--perturbatively stable 2D quantum gravity coupled to the models is studied. Global KdV flows between th…
Stable Non--Perturbative Minimal Models Coupled to 2D Quantum Gravity
Clifford Johnson, Tim Morris, Bill Spence
A generalisation of the non--perturbatively stable solutions of string equations which respect the KdV flows, obtained recently for the conformal minimal models coupled…
