3-环面上结点集的涨落和一般相消现象

Fluctuations of nodal sets on the 3-torus and general cancellation phenomena

Massimo Notarnicola

摘要:

在2017年,Benatar和Maffucci arXiv:1708.07015建立了一个在高能极限下3-torus上算术随机波的节面方差的渐近定律。在随后的工作中,Cammarota arXiv:1708.07679证明了节面的通用非高斯极限定理。本文研究了3-环面上两个和三个独立的同频算术随机波的节交长度和节交点数。对于这些量,我们计算它们的期望值,渐近方差以及它们的极限分布。我们的结果是基于体积的Wiener-Itô展开,自然补充了Cammarota arXiv:1708.07679的发现。在我们的分析的核心在于一个抽象的取消现象适用于任意高斯随机场的水平集的研究,我们相信有独立的利益。

英文摘要:

In 2017, Benatar and Maffucci arXiv:1708.07015 established an asymptotic law for the variance of the nodal surface of arithmetic random waves on the 3-torus in the high-energy limit. In a subsequent work, Cammarota arXiv:1708.07679 proved a universal non-Gaussian limit theorem for the nodal surface. In this paper, we study the nodal intersection length and the number of nodal intersection points associated, respectively, with two and three independent arithmetic random waves of same frequency on the 3-torus. For these quantities, we compute their expected value, asymptotic variance as well as their limiting distribution. Our results are based on Wiener-Itô expansions for the volume and naturally complement the findings of Cammarota arXiv:1708.07679. At the core of our analysis lies an abstract cancellation phenomenon applicable to the study of level sets of arbitrary Gaussian random fields, that we believe has independent interest.
