The stable trees are nested

Abstract

We show that we can construct simultaneously all the stable trees as a nested family. More precisely, if 1<a<a21 < a < a' \leq 2 we prove that hidden inside any a-stable we can find a version of an a'-stable tree rescaled by an independent Mittag-Leffler type distribution. This tree can be explicitly constructed by a pruning procedure of the underlying stable tree or by a modification of the fragmentation associated with it. Our proofs are based on a recursive construction due to Marchal which is proved to converge almost surely towards a stable tree.
