摘要

本文讨论了一个简单的问题:典型的随机矩阵范围是什么样子的?我们一方面研究了算子元组的各种收敛模式与矩阵范围相对于豪斯多夫度量的连续性之间的关系。特别地,我们证明了生成C*-代数的连续域的元组的矩阵范围是连续的,在Hausdorff度量中的每个级别都是连续的。利用这一观察结果以及矩阵系综分布中的强收敛性的已知结果,我们确定了独立Wigner或Haar系综的矩阵范围收敛到的极限矩阵范围。

On the matrix range of random matrices
This note treats a simple minded question: \textit{what does a typical random matrix range look like?} We study the relationship between various modes of convergence for tuples of operators on the one hand, and continuity of matrix ranges with respect to the Hausdorff metric on the other. In particular, we show that the matrix range of a tuple generating a continuous field of C∗-algebras is continuous in the sense that every level is continuous in the Hausdorff metric. Using this observation together with known results on strong convergence in distribution of matrix ensembles, we identify the limit matrix ranges to which the matrix ranges of independent Wigner or Haar ensembles converge.
