Abstract:

A well-known theorem of Rodin & Sullivan, previously conjectured by Thurston, states that the circle packing of the intersection of a lattice with a simply connected planar domainΩinto the unit disc D converges to a Riemann map fromΩto D when the mesh size converges to 0. An analogous statement holds when circle packings are replaced by the square tilings of Brooks et al. The latter provides an algorithm for the approximation of the Riemann map from an arbitrary domain. The theory of random walks and electrical networks comes into play.

Joint work with Christoforos Panagiotis (Geneva)
