Physics Group Meeting at IAS | Baurzhan Mukhametzhanov, IAS | “Matrix Models and Minimal Liouville Gravity” | Bloomberg Lecture Hall

I will review some old ideas about the duality between matrix models and Liouville theory coupled to a  (p,q) minimal model. In this approach t'Hooft diagrams of the matrix model are thought of as a discretization of a 2d surface. Fine-tuning of the coupling constant leads to divergence of the perturbative expansion. In this limit dense t'Hooft diagrams dominate and become a good approximation of a smooth 2d surface.
