Abstract

We consider a vertex reinforced random walk on the integer lattice with sub-linear reinforcement. Under some assumptions on the regular variation of the weight function, we characterize whether the walk gets stuck on a finite interval. When this happens, we estimate the size of the localization set. In particular, we show that, for any odd number \(N\) larger than or equal to \(5\), there exists a vertex reinforced random walk which localizes with positive probability on exactly \(N\) consecutive sites.
