论文摘要
我们在具有单数领先块的马鞍点矩阵的特征值上得出界限。举证技术基于增强。我们的边界取决于矩阵块的范围或内核之间的主要角度。数值实验验证了我们的分析结果。
We derive bounds on the eigenvalues of saddle-point matrices with singular leading blocks. The technique of proof is based on augmentation. Our bounds depend on the principal angles between the ranges or kernels of the matrix blocks. Numerical experiments validate our analytical findings.
