随机矩阵的通用和积规则

Universal sum and product rules for random matrices

Tim Rogers

摘要:

随机矩阵的谱密度研究通过四元数广义的格林函数,它精确地描述了一个特定类型的随机扰动下的给定矩阵的平均谱密度。在高维极限中,找到了与确定性矩阵求和或相乘时具有独立项的随机矩阵的四元数格林函数的精确和通用表达式。由此,可以准确地预测极限谱密度。

英文摘要:

The spectral density of random matrices is studied through a quaternionic generalisation of the Green's function, which precisely describes the mean spectral density of a given matrix under a particular type of random perturbation. Exact and universal expressions are found in the high-dimension limit for the quaternionic Green's functions of random matrices with independent entries when summed or multiplied with deterministic matrices. From these, the limiting spectral density can be accurately predicted.
