摘要
研究了给定度序列(d1,…)的构型模型上的简单随机漫步问题。, d nn),研究其空集在水平u >0 0的连通分量。我们证明了最大连通分量的大小在u *水平上表现出一个相变,这个相变可以与某一Galton-Watson树上随机交错的临界参数有关。我们进一步证明了在u *周围存在一个大小为n−1/3的临界窗口,其中空集的最大连通分量具有类似于临界Erdős-Rényi随机图的度量空间缩放极限。
Critical window for the vacant set left by random walk on the configuration model
We study the simple random walk on the configuration model with given degree sequence (d1 , . . . , d n n) and investigate the connected components of its vacant set at level u > 0. We show that the size of the maximal connected component exhibits a phase transition at level u∗ which can be related with the critical parameter of random interlacements on a certain Galton-Watson tree. We further show that there is a critical window of size n−1/3 around u∗ in which the largest connected components of the vacant set have a metric space scaling limit resembling the one of the critical Erdős-Rényi random graph.
