Abstract

We study some properties of the ultrametric tree structure associated with the directed polymer problem. We find that the exponents 2/3 and 1/3 appear in a natural way in the description of the tree. Some of our results explain earlier numerical results of Zhang in the problem of the stability of the best directed polymer configuration to small perturbations.
