Abstract:  Abstract: An infinite graph may have the property that two independent random walks on the graph  never meet each other, although each of them visits every vertex of the graph infinitely often. I shall describe some old results joint with Yuval Peres and later results of Barlow, Peres and Sousi. Finally I shall report some ongoing recent investigations in this direction.
