独立非Hermite随机矩阵的乘积

Products of Independent Non-Hermitian Random Matrices

Sean O'Rourke, Alexander Soshnikov

摘要:

对于固定的$m>1$,我们考虑$m$独立的$n \times n$非厄米特随机矩阵$X_1, ..., X_m$,i.i.d.中心条目与有限$(2+η)$ -th时刻,$ η>0.$作为$n$趋于无穷大,我们表明,经验谱分布的$n^{-m/2} \*X_1 X_2 ... X_m$收敛,概率为1,一个非随机的,旋转不变的分布与紧支持在复平面。极限分布是圆形定律的$m$次幂。

英文摘要:

For fixed $m>1$, we consider $m$ independent $n \times n$ non-Hermitian random matrices $X_1, ..., X_m$ with i.i.d. centered entries with a finite $(2+η)$-th moment, $ η>0.$ As $n$ tends to infinity, we show that the empirical spectral distribution of $n^{-m/2} \*X_1 X_2 ... X_m$ converges, with probability 1, to a non-random, rotationally invariant distribution with compact support in the complex plane. The limiting distribution is the $m$-th power of the circular law.
