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.

Random ultrametric trees and applications [PDF]

open access: yesESAIM: Proceedings and Surveys, 2017
Ultrametric trees are trees whose leaves lie at the same distance from the root. They are used to model the genealogy of a population of particles co-existing at the same point in time.

Unimodular Random Trees [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2012
We 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.

Limits of Random Trees [PDF]

open access: yesActa Mathematica Hungarica, 2014
Local convergence of bounded degree graphs was introduced by Benjamini and Schramm. This result was extended further by Lyons to bounded average degree graphs.

Width and mode of the profile for some random trees of logarithmic height

open access: yesAnnals of Applied Probability, 2006
We propose a new, direct, correlation-free approach based on central moments of profiles to the asymptotics of width (size of the most abundant level) in some random trees of logarithmic height.

Profiles of random trees: plane-oriented recursive trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We summarize several limit results for the profile of random plane-oriented recursive trees. These include the limit distribution of the normalized profile, asymptotic bimodality of the variance, asymptotic approximations of the expected width and the ...

On random trees and forests [PDF]

open access: yesESAIM: Proceedings and Surveys, 2023
The first talk at the session Random trees and random forests “Journée MAS” (27/08/2021) was presented by I. Kortchemski. After a general up-to-date introduction to local and scaling limits of Bienaymé trees (which are discrete branching trees), he ...

Conditioned Galton-Watson trees do not grow [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
An example is given which shows that, in general, conditioned Galton-Watson trees cannot be obtained by adding vertices one by one, while this can be done in some important but special cases, as shown by Luczak and Winkler.

Random Records and Cuttings in Split Trees: Extended Abstract [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We study the number of records in random split trees on $n$ randomly labelled vertices. Equivalently the number of random cuttings required to eliminate an arbitrary random split tree can be studied.
