The coward random walk.

Abstract:

Joint work with Itai Benjamini and Gady Kozma.

We study the "coward" walk - an excited random walk on $\Z^3_+$, which gets a push downward eac time it reaches a new vertex, and behaves like a SRW when it reaches a vertex it has visited before. (With reflection upward on the plane $z=0$). We analyse the case where the push recieved is combinatorial - i.e. each time a new vertex is reaches, the walker goes down with probability 1, and show that this walk is recurrent. We also analize it's behaviour in terms of number of returns to 0.
