随机块Toeplitz和Hankel矩阵特征值的极限分布

Limit Distributions of Eigenvalues for Random Block Toeplitz and Hankel Matrices

Yi-Ting Li, Dang-Zheng Liu, Zheng-Dong Wang

摘要:

块Toeplitz和Hankel矩阵在许多方面的应用。本文将研究几种模型的特征值分布,并得到其特征值分布规律。首先给出块Toeplitz矩阵和块Hankel矩阵的迹公式。然后证明了随机块Toeplitz(Hankel)矩阵特征值分布的几乎必然极限$γ_{_T}^{(m)}$ $(γ_{_H}^{(m)})$的存在性,并给出了极限分布的矩,其中$m$是块的阶.然后证明了随机块Toeplitz和Hankel带状矩阵特征值分布的几乎必然极限的存在性,并给出了极限分布的矩。最后证明了$γ_{_T}^{(m)}$ $(γ_{_H}^{(m)})$和$m\ra\iy$一样弱收敛于循环律.

英文摘要:

Block Toeplitz and Hankel matrices arise in many aspects of applications. In this paper, we will research the distributions of eigenvalues for some models and get the semicircle law. Firstly we will give trace formulae of block Toeplitz and Hankel matrix. Then we will prove that the almost sure limit $γ_{_T}^{(m)}$ $(γ_{_H}^{(m)})$ of eigenvalue distributions of random block Toeplitz (Hankel) matrices exist and give the moments of the limit distributions where $m$ is the order of the blocks. Then we will prove the existence of almost sure limit of eigenvalue distributions of random block Toeplitz and Hankel band matrices and give the moments of the limit distributions. Finally we will prove that $γ_{_T}^{(m)}$ $(γ_{_H}^{(m)})$ converges weakly to the semicircle law as $m\ra\iy$.
