Kingman结合树的Horton自相似性

Horton self-similarity of Kingman's coalescent tree

Yevgeniy Kovchegov, Ilya Zaliapin

摘要:

本文建立了Kingman合并过程的树表示的弱Horton自相似性。证明是基于一个Smoluchowski型系统的常微分方程的分支数的一个给定的Horton-Strahler顺序在一棵树,代表金曼的N-聚结过程中的一个常数的内核,在流体动力学的限制。我们还证明了一个密切的联系之间的组合金曼树和组合水平集树的白噪声,这意味着霍顿自相似性为后者。

英文摘要:

The paper establishes a weak version of Horton self-similarity for a tree representation of Kingman's coalescent process. The proof is based on a Smoluchowski-type system of ordinary differential equations for the number of branches of a given Horton-Strahler order in a tree that represents Kingman's N-coalescent process with a constant kernel, in a hydrodynamic limit. We also demonstrate a close connection between the combinatorial Kingman's tree and the combinatorial level set tree of a white noise, which implies Horton self-similarity for the latter.
