Title: Universal Formulae for Correlators of a Broad Class of Models
Abstract:
A new and strikingly simple procedure for deriving universal formulae for correlation functions in a broad class of models will be presented. Physics applications include double-scaled random matrix models, low-dimensional models of gravity and supergravity, various minimal string theories, and the low-temperature, near-horizon quantum dynamics of certain black holes. Mathematical applications include computations in intersection theory on the compactified moduli space of (super)Riemann surfaces of genus g and n boundaries, as well as evaluations of its volume. In certain supersymmetric cases, the new procedure provides swift derivations of some remarkable closed-form formulae from the mathematical literature, and readily yields new closed-form expressions.
