随机交错空集的连通性界

Connectivity Bounds for the Vacant Set of Random Interlacements

Vladas Sidoravicius, Alain-Sol Sznitman

摘要:

最近在arXiv:0704.2560中引入了Z^d(d大于或等于3)上的随机交错的模型。非负参数u参数化Z^d上的随机交错的密度。在本说明中,我们研究了在非退化状态下,由水平u处的随机交织留下的空集的连通性,其中u大于空集渗流的非退化临界参数,参见arXiv:0704.2560,arXiv:0808.3344。我们证明了一个拉伸指数衰减的连通性函数的空集在水平u,当u大于其他关键参数。这两个关键参数是否实际上一致,目前仍是一个悬而未决的问题。

英文摘要:

The model of random interlacements on Z^d, d bigger or equal to 3, was recently introduced in arXiv:0704.2560. A non-negative parameter u parametrizes the density of random interlacements on Z^d. In the present note we investigate the connectivity properties of the vacant set left by random interlacements at level u, in the non-percolative regime, where u is bigger than the non-degenerate critical parameter for percolation of the vacant set, see arXiv:0704.2560, arXiv:0808.3344. We prove a stretched exponential decay of the connectivity function for the vacant set at level u, when u is bigger than an other critical parameter. It is presently an open problem whether these two critical parameters actually coincide.
