Unimodular random trees [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2013
AbstractWe consider unimodular random rooted trees (URTs) and invariant forests in Cayley graphs. We show that URTs of bounded degree are the same as the law of the component of the root in an invariant percolation on a regular tree. We use this to give a new proof that URTs are sofic, a result of Elek.

Random ancestor trees [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2010
We investigate a network growth model in which the genealogy controls the evolution. In this model, a new node selects a random target node and links either to this target node, or to its parent, or to its grandparent, etc; all nodes from the target node to its most ancient ancestor are equiprobable destinations.

Random Trees in Random Graphs [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
We show that a random labeled n n -vertex graph almost surely contains isomorphic copies of almost all labeled n n -vertex trees, in two senses. In the first sense, the probability of each edge occurring in the graph diminishes as n n increases, and the set of trees referred to as "almost all" depends

Fragmentation of random trees [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2014
We study fragmentation of a random recursive tree into a forest by repeated removal of nodes. The initial tree consists of N nodes and it is generated by sequential addition of nodes with each new node attaching to a randomly-selected existing node. As nodes are removed from the tree, one at a time, the tree dissolves into an ensemble of separate trees,

Random Hyperplane Search Trees

open access: yesSIAM Journal on Computing, 2009
Summary: A hyperplane search tree is a binary tree used to store a set \(S\) of \(n\) \(d\)-dimensional data points. In a random hyperplane search tree for \(S\), the root represents a hyperplane defined by \(d\) data points drawn uniformly at random from \(S\).

Random Recursive Trees and Preferential Attachment Trees are Random Split Trees [PDF]

open access: yesCombinatorics, Probability and Computing, 2018
We consider linear preferential attachment trees, and show that they can be regarded as random split trees in the sense of Devroye (1999), although with infinite potential branching. In particular, this applies to the random recursive tree and the standard preferential attachment tree.
