实高斯零点的方差线性

Variance linearity for real Gaussian zeros

Raphaël Lachièze-Rey

摘要:

本文研究了实数直线上平稳高斯过程的零点集,特别给出了大区间上点个数方差的下界。我们证明了该点过程决不是超一致的,即方差至少是线性的,并给出了方差是线性的必要条件,这些条件接近于尖锐。我们研究了一类对称的Bernoulli卷积,并给出了一个例子,其中零点集是超刚性的,弱混合的,而不是超一致的。

英文摘要:

We investigate the zero set of a stationary Gaussian process on the real line, and in particular give lower bounds for the variance of the number of points on a large interval, in all generality. We prove that this point process is never hyperuniform, i.e. the variance is at least linear, and give necessary conditions to have linear variance, which are close to be sharp. We study the class of symmetric Bernoulli convolutions and give an example where the zero set is super rigid, weakly mixing, and not hyperuniform.
