Abstract

Let WW be an integer valued random variable satisfying E[W]=:δ0E[W] =: \delta \geq 0 and P(W<0)>0P(W<0)>0, and consider a self-interacting random walk that behaves like a simple symmetric random walk with the exception that on the first visit to any integer xZx\in \mathbb{Z} the size of the next step is an independent random variable with the same distribution as WW. We show that this self-interacting random walk is recurrent if δ1\delta\leq 1 and transient if δ>1\delta>1. This is a special case of our main result which concerns the recurrence and transience of excited random walks (or cookie random walks) with non-nearest neighbor jumps.
