随机隔行的占用时间分布的大偏差

Large deviations for occupation time profiles of random interlacements

Xinyi Li, Alain-Sol Sznitman

摘要:

本文导出了在Z^d(d ≥ 3)的大盒子中,在固定水平上随机交错的占据时间密度分布的大偏差原理。作为一个应用,我们分析了概率的渐近行为,高值的密度分布绝缘的宏观体在一个大盒子。作为程序的一个步骤,我们得到了一个类似的大偏差原理,适用于R^d的大盒子中的布朗交错在固定水平上的占据-时间测度,并基于对某些薛定谔半群的分析,得到了占据-时间测度的拉普拉斯变换的一个新恒等式.

英文摘要:

We derive a large deviation principle for the density profile of occupation times of random interlacements at a fixed level in a large box of Z^d, with d bigger or equal to 3. As an application, we analyze the asymptotic behavior of the probability that atypically high values of the density profile insulate a macroscopic body in a large box. As a step in this program, we obtain a similar large deviation principle for the occupation-time measure of Brownian interlacements at a fixed level in a large box of R^d, and we derive a new identity for the Laplace transform of the occupation-time measure, which is based on the analysis of certain Schrödinger semi-groups.
