DESCRIPTION:Abstract: We investigate the behaviour of random walk on the c
 ircle packing of a hyperbolic unimodular triangulations. A way to relate t
 he geometry of such graphs with random walks is via circle packing: one\nc
 an draw non-intersecting circles on the plane\, one for each vertex and ci
 rcles touch each other if and only if their vertices are adjacent.  We sho
 w that such a triangulation can be packed in the unit disc and the unit ci
 rcle gives a pretty accurate description of the final behaviour of the sim
 ple random walk on it. Joint work with Omer Angel\, Tom Hutchcroft and Asa
 f Nachmias.
