Anna Lytova, Leonid Pastur

摘要:

当矩阵的带宽和秩同时趋于无穷大时,得到了非对称带状随机矩阵奇异值的归一化分布在极限下的Stieltjes变换方程.给出了这一极限满足四分之一圆律的条件,并考虑了下三角随机矩阵的一个有趣的特殊情况,给出了相应的极限奇异值分布的某些性质。

英文摘要:

An equation is obtained for the Stieltjes transform of the normalized distribution of singular values of non-symmetric band random matrices in the limit when the band width and rank of the matrix simultaneously tend to infinity. Conditions under which this limit agrees with the quarter-circle law are found. An interesting particular case of lower triangular random matrices is also considered and certain properties of the corresponding limiting singular value distribution are given.
