Title: Substrative random forests.

础产蝉迟谤补肠迟.听Motivated by online recommendation systems, we study a family of
random forests. The vertices of the forest are labeled by integers. Each non-positive
integer is the root of a tree. Vertices labeled by positive integers n are attached
sequentially such that the parent of vertex n is n鈭抁_n, where the Z_n are i.i.d.
positive integer-valued random variables. We study several characteristics of the resulting
random forest, including survival and extinction of the trees.聽

The talk is based on joint work with
Nicolas Broutin, Luc Devroye, and Roberto Imbuzeiro Oliveira.
