AI总结:

本文研究了伯努利渗流中化学距离的超浓度现象,通过动态有效半径和晶格动物理论量化了测地线的混沌行为。

摘要:

我们研究了超临界伯努利渗流在$\mathbb{Z}^d$上的化学距离。最近,Dembin [Dem22] 显示化学距离表现出亚线性方差,这一现象现在被称为超浓度。在本文中,我们建立了这一现象与在小扰动配置下测地线的混沌行为之间的等价性,从而验证了Chatterjee在伯努利渗流背景下将异常波动与混沌联系起来的一般原则。我们的方法依赖于一种动态的有效半径,这一概念最初在[CN25]中提出,用于测量给定边的权重可能为无限的共影响。结合晶格动物理论中的技术,这种方法使我们能够通过原始和扰动测地线之间的重叠来量化边的总共影响。

英文摘要:

We study the chemical distance of supercritical Bernoulli percolation on $\mathbb{Z}^d$. Recently, Dembin [Dem22] showed that the chemical distance exhibits sublinear variance, a phenomenon now referred to as superconcentration. In this article, we establish an equivalence between this phenomenon and chaotic behavior of geodesics under small perturbations of the configuration, thereby confirming Chatterjee's general principle relating anomalous fluctuations to chaos in the context of Bernoulli percolation. Our methods rely on a dynamical version of the effective radius, refining the notion first proposed in [CN25], in order to measure the co-influence of a given edge whose weight may be infinite. Together with techniques from the theory of lattice animals, this approach allows us to quantify the total co-influence of edges in terms of the overlap between original and perturbed geodesics.
