关于布朗单矩阵的特征值

On eigenvalues of the Brownian sheet matrix

Jian Song, Yimin Xiao, Wangjun Yuan

摘要:

本文导出了以布朗单为元素的对称矩阵的特征值所满足的随机偏微分方程组。我们证明了重标度矩阵的经验谱测度序列$\left\{L_{d}(s,t), (s,t)\in[0,S]\times [0,T]\right\}_{d\in\mathbb N}$在$C([0,S]\times [0,T], \mathcal P(\mathbb R))$上是紧的,因此当$d$趋于无穷大时,根据Wigner循环律是收敛的.我们还得到了高维极限测度所满足的偏微分方程。

英文摘要:

We derive a system of stochastic partial differential equations satisfied by the eigenvalues of the symmetric matrix whose entries are the Brownian sheets. We prove that the sequence $\left\{L_{d}(s,t), (s,t)\in[0,S]\times [0,T]\right\}_{d\in\mathbb N}$ of empirical spectral measures of the rescaled matrices is tight on $C([0,S]\times [0,T], \mathcal P(\mathbb R))$ and hence is convergent as $d$ goes to infinity by Wigner's semicircle law. We also obtain PDEs which are satisfied by the high-dimensional limiting measure.
