The Pearcey process is a universal point process in random matrix theory and depends on a parameter ρ ∈ ℝ . Let N ( x ) be the random variable that counts the number of points in this process that fall in the interval [ − x , x ] . In this note, we establish the following global rigidity upper bound:
lim s → ∞ ℙ sup x > s N ( x ) − 3 3 4 π x 4 3 − 3 ρ 2 π x 2 3 log x ≤ 4 2 3 π + 𝜖 = 1 ,
where 𝜖 > 0 is arbitrary. We also obtain a similar upper bound for the maximum deviation of the points, and a central limit theorem for the individual fluctuations. The proof is short and combines a recent result of Dai, Xu and Zhang with another result of Charlier and Claeys.

Pearcey 过程的最大偏差的上限
Pearcey 过程是随机矩阵理论中的一个通用点过程,它依赖于一个参数ρ ∈ ℝ . 让ñ ( X ) 是计算此过程中落在区间内的点数的随机变量[ - X , X ] . 在本说明中,我们建立了以下全局刚性上限:
林 s → ∞ ℙ 支持 X > s ñ ( X ) - 3 3 4 π X 4 3 - 3 ρ 2 π X 2 3 日志 X ≤ 4 2 3 π + 𝜖 = 1 ,
在哪里𝜖 > 0 是任意的。我们还获得了点的最大偏差的类似上限,以及单个波动的中心极限定理。证明很简短,将 Dai、Xu 和 Zhang 的最新结果与 Charlier 和 Claeys 的另一个结果相结合。
