On a Result of David Aldous Concerning the Trees in a Conditioned Excursion
Jon Warren, University of Warwick
Abstract
The law of a random tree constructed within a Brownian
excursion is calculated conditional on knowing the occupation measure of
the excursion. In previous work David Aldous has used random walk
approximations to obtain this result. Here it is deduced from
Le Gall's description of the tree in the unconditioned excursion.
