Webbe the effective resistance between nodes i and j (i.e., 1/Rq is the current that would flow from i to j if one volt were applied between i and j; it is known that 1/Rq ~ a0. ). Let the resistive random walk be defined by the probabilities pq = aq/~t ~it. In Section 3 we show that this random walk has Weba random walk is determined by the resistance from the origin to cut sets at arbitrary distance from the origin [13]. In finite graphs the resistances determine hitting times of …

WebWe will see that there is a relation between the induced voltages, and random walks in a graph. We will also see how to compute the induced voltages by solving systems of equations in Laplacians. 8.2 Resistor Networks Given a graph, we can treat each edge as a resistor. If the graph is unweighted, we will assume that the resistor has resistance 1. http://cs.yale.edu/homes/spielman/462/2007/lect8-07.pdf
