摘要
考虑一个临界Erdős-Rényi随机图:为顶点数,条可能边中的每一条独立地以概率保留在图中,其中是一个固定实数。当趋于无穷时,Addario-Berry、Broutin和Goldschmidt已经证明,连通分量集合(视为适当归一化的带度量的紧致度量空间)依分布收敛到一个由随机实图构成的连续极限。在本文中,我们主要考虑临界Erdős-Rényi随机图上的动态渗流。每对顶点附着一个强度为的泊松过程,每次触发时重新采样对应的边。在此过程下,连通分量集合发生并合和碎裂。我们证明,当趋于无穷时,该过程依分布收敛到连续极限上的一个碎裂-并合过程。我们还证明了离散并合和碎裂过程的收敛性,并给出了与碎裂和并合相关的Feller型性质。

备注
The organization has changed. Some important mistakes have been corrected: - Now, the usual Skorokhod topology is used (cf. appendix A). - a mistake in Lemma 4.10 (iii) (old numbering) is corrected now in Lemma 5.9 (new numbering). - there was an error, now fixed, concerning the control of supdiam in section 5.4. - Lemma 2.5 (old numbering) as stated was false, a corrected version replaces it
