We consider a system of particles which perform branching Brownian motion with negative drift and are killed upon reaching zero, in the near-critical regime where the total population …
Probability modelling for DNA sequence evolution is well established and provides a rich framework for understanding genetic variation between samples of individuals from one or …
A PROBABILISTIC PROOF OF A WEAK LIMIT LAW FOR THE NUMBER OF CUTS NEEDED TO ISOLATE THE ROOT OF A RANDOM RECURSIVE TREE 1 Introdu Page 1 Elect. Comm. in …
Let Xn be the number of cuts needed to isolate the root in a random recursive tree with n vertices. We provide a weak convergence result for Xn. The basic observation for its proof is …

The class of coalescent processes with simultaneous multiple collisions (Ξ-coalescents) without proper frequencies is considered. We study the asymptotic behavior of the external …
We give the asymptotic distribution of the length of partial coalescent trees for Beta and related coalescents. This allows us to give the asymptotic distribution of the number of …

We examine the total number of collisions $ C_n $ in the $\Lambda $-coalescent process which starts with $ n $ particles. A linear growth and a stable limit law for $ C_n $ are shown …
We derive the asymptotic distribution of the total length L_n of a Beta(2-α,α)-coalescent tree for 1<α<2, starting from n individuals. There are two regimes: If α≤12(1+5), then L_n …

We consider a coalescent process as a model for the genealogy of a sample from a population. The population is subject to neutral mutation at constant rate ρ per individual …
