论文摘要
我们展示了一种简单的方法来构建较大的矩阵但保留光谱半径。这得出了两个任意维度的两个平方矩阵的足够标准具有相同的光谱半径，一种比较两个矩阵的光谱半径的方法，以及一种在光谱半径上得出新的上和下限的方法，从而使标准行总和界限为特殊情况。
We show a simple method for constructing larger matrices but preserving the spectral radius. This yields a sufficient criteria for two square matrices of arbitrary dimension have the same spectral radius, a way to compare spectral radii of two matrices, and a way to derive new upper and lower bounds on spectral radius which give the standard row sum bounds as a special case.
