对于处于平衡状态的大种群的系谱学,一个已经建立的模型是金曼的聚结模型。对于随时间演化的种群及其谱系,这产生了时间平稳的树值过程。我们研究的总和的分支长度,简称为树长,并证明了(适当补偿)序列的树长过程收敛,作为人口规模趋于无穷大,一个极限过程càdlàg路径,无穷小方差,和Gumbel分布作为其平衡点。
A well-established model for the genealogy of a large population in equilibrium is Kingman’s coalescent. For the population together with its genealogy evolving in time, this gives rise to a time-stationary tree-valued process. We study the sum of the branch lengths, briefly denoted as tree length, and prove that the (suitably compensated) sequence of tree length processes converges, as the population size tends to infinity, to a limit process with càdlàg paths, infinite infinitesimal variance, and a Gumbel distribution as its equilibrium.
