Title
Measurable events indexed by products of trees
Abstract
tree T is said to be homogeneous if it is uniquely rooted and there exists an integer b 2, called the branching number of T , such that every t T has exactly b immediate successors. A vector homogeneous tree T is a finite sequence ( T 1,..., T d ) of homogeneous trees and its level product T is the subset of the Cartesian product T 1 ... T d consisting of all finite sequences ( t 1,..., t d ) of nodes having common length.We study the behavior of measurable events in probability spaces indexed by the level product T of a vector homogeneous tree T . We show that, by refining the index set to the level product S of a vector strong subtree S of T , such families of events become highly correlated. An analogue of Lebesgue's density Theorem is also established which can be considered as the "probabilistic" version of the density Halpern-Läuchli Theorem.
