随机矩阵部分迹的泛函CLT

A functional CLT for partial traces of random matrices

Jan Nagel

摘要:

本文证明了$f(Z)$的第一个$\lfloor t n \rfloor$对角元素之和作为$t$中的函数的泛函中心极限定理,其中$Z$是随机实对称或复Hermitian $n\times n$矩阵.当线性本征值统计量$\operatorname{tr} f(Z)$满足CLT时,该结果适用于$Z$的正交或酉不变分布。极限过程在作为$f(Z)_{1,1}$的各个矩阵元素的波动和线性特征值统计之间插值。它也可以被看作是一个功能CLT的随机加权措施的过程。

英文摘要:

In this paper we show a functional central limit theorem for the sum of the first $\lfloor t n \rfloor$ diagonal elements of $f(Z)$ as a function in $t$, for $Z$ a random real symmetric or complex Hermitian $n\times n$ matrix. The result holds for orthogonal or unitarily invariant distributions of $Z$, in the cases when the linear eigenvalue statistic $\operatorname{tr} f(Z)$ satisfies a CLT. The limit process interpolates between the fluctuations of individual matrix elements as $f(Z)_{1,1}$ and of the linear eigenvalue statistic. It can also be seen as a functional CLT for processes of randomly weighted measures.
