Math Colloquium

Speaker: François David
Title: Planar maps, circle patterns and 2D gravity

Location: V-157, VRII.
Time: Friday, March 11 at 13:20.

Abstract:

I present a model of random planar triangulations (planar maps) based on circle patterns and discuss its properties. It exemplifies the relations between discrete random geometries in the plane, conformally invariant point processes and two dimensional quantum gravity (Liouville theory and topological gravity).
