Random walk on trees and graphs has been the subject of intensive research during the last decade. Many deep and elegant results have been obtained but the subject is currently still under vigorous development. Trees and Graphs arise naturally in many situations, including in combinatorics, mathematical physics, and computer network.

In this course, we will survey some of the recent development of the past decade. We will study random walks, electronic networks, recurrence, transience and speed of random walks, relations between random walks, certain flows on trees; dimensional and capacity results, percolation on trees, branching processes, and other topics.

Prerequisites: Knowledge of elementary measure theory at the level of Math 426.
