本文研究非厄米随机矩阵的乘性变形的谱性质,考虑形如$\boldsymbol{A}\boldsymbol{B}$的矩阵,其中$\boldsymbol{A}$为$N\times N$确定性矩阵(不一定是厄米矩阵),$\boldsymbol{B}$为旋转不变随机矩阵。我们证明,当$N\to\boldsymbol{\boldsymbol{B}}$的$\boldsymbol{\boldsymbol{R}}_1$和$\boldsymbol{\boldsymbol{R}}_2$变换的简单方程决定。
英文摘要
In this paper, we study spectral properties of multiplicative deformations of non-Hermitian random matrices. We consider matrices of the form $\mathbf{A}\mathbf{B}$, where $\mathbf{A}$ is a deterministic $N\times N$ matrix (not necessarily Hermitian) and $\mathbf{B}$ is a rotationally invariant random matrix. We show that, as $N\to\infty$, the boundary of the complex eigenvalue distribution of $\mathbf{A}\mathbf{B}$ is governed by simple equations involving the $\mathcal{R}_1$ and $\mathcal{R}_2$ transforms of $\mathbf{B}$.
