罕见生存条件下的分枝随机游动

Branching random walks conditioned on rarely survival

Tianyi Bai, Pierre Rousselin

摘要:

在本文中,我们证明了一个Galton-Watson树的条件下,有一个固定数量的粒子生成$n$收敛的分布为$n\rightarrow\infty$,并与此工具,我们研究的跨度和间隙统计的分支随机游动在这样的树,这是离散版本的Ramola,Majumdar和Schehr 2015年,推广到任意后代和位移分布与力矩约束。

英文摘要:

In this paper, we show that a Galton-Watson tree conditioned to have a fixed number of particles in generation $n$ converges in distribution as $n\rightarrow\infty$, and with this tool we study the span and gap statistics of a branching random walk on such trees, which is the discrete version of Ramola, Majumdar and Schehr 2015, generalized to arbitrary offspring and displacement distributions with moment constraints.
