Optimal co-adapted coupling for the symmetric random walk on the hypercube

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/171525Let X and Y be two simple symmetric continuous-time random walks on the vertices of the n-dimensional hypercube. We consider the class of co-adapted couplings of these processes, and describe an intuitive coupling which is shown to be the fastest in this class.14 pages; added references and publication informationProbability93E20(Primary); 60J27(Secondary)Optimal co-adapted coupling for the symmetric random walk on the hypercubetext
