Abstract
In this survey paper we mainly discuss the results contained in two of our recent articles [2] and [5]. Let t≥0 be a continuoustime, symmetric, nearestneighbour random walk on Zd. For every T > 0 we define the transformed
path measure dPT = (1/ZT ) exp(HT ) dP, where P is the original one and ZT is the appropriate normalizing constant. The Hamiltonian HT imparts the selfattracting
interaction of the paths up to time T. We consider the case where HT is given by a potential function V on Zd with finite support, and the case HT = −NT , where NT denotes the number of points visited by the random walk up to time T. In both cases the typical paths under PT as T →∞ clump together much more than those of the free random walk and give rise to localization phenomena.
