摘要:

当度分布具有无穷大三阶矩时,我们建立了组态模型临界窗口中最大连通分量的全局质量下界性质。临界逾渗簇的标度极限被看作是可测的度量空间,在[7]中关于Gromov-弱拓扑建立。我们的结果扩展了这些缩放极限的结果,更强的Gromov-Hausdorff-Prokhorov拓扑结构的程度分布的假设略强。这意味着全局泛函的分布收敛性,如最大临界分量的直径。此外,我们的结果给出了一个充分条件紧的随机度量空间,出现的标度极限的临界集群在重尾制度。

英文摘要:

We establish the global lower mass-bound property for the largest connected components in the critical window for the configuration model when the degree distribution has an infinite third moment. The scaling limit of the critical percolation clusters, viewed as measured metric spaces, was established in [7] with respect to the Gromov-weak topology. Our result extends those scaling limit results to the stronger Gromov-Hausdorff-Prokhorov topology under slightly stronger assumptions on the degree distribution. This implies the distributional convergence of global functionals such as the diameter of the largest critical components. Further, our result gives a sufficient condition for compactness of the random metric spaces that arise as scaling limits of critical clusters in the heavy-tailed regime.
