Abstract | |||||||||
| A random walk on Z^d is excited if the first time it visits a vertex there is a bias in one direction, but on subsequent visits to that vertex the walker picks a neighbor uniformly at random. We show that excited random walk on Z^d, is transient iff d>1.. Comment: 7 pages, v2 is journal version | |||||||||
