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.

  1. Extended JT supergravity and random matrix models: The power of the string equation

    hep-th 2025-07 conditional novelty 7.0 of 10

    The string equation, with simple analyticity requirements, determines BPS sectors from non-BPS sectors and yields matrix model descriptions for N=3 and large N=4 JT supergravity.

  2. Instanton-Induced Closed-String Amplitudes in Minimal Superstring Theory at Subleading Order

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    Explicit computation of instanton-induced amplitudes in minimal superstring theories at subleading order, after regulating open-string degenerations with string field theory, yields exact agreement with DDK-KPZ scaling.
