关于正定厄米特矩阵的Schur补的迹和特征值的不等式

THE INEQUALITY ON TRACE AND EIGENVALUES OF THE SCHUR COMPLEMENT OF A POSITIVE SEMIDEFINITE HERMITIAN MATRIX

本文研究了正定厄米特矩阵Schur补的迹和特征值的性质,通过一个不等式的证明,得到了正定厄米特矩阵和的Schur补与正定厄米特矩阵Schur补的和的迹和特征值之间的不等式.

In this paper, we study the trace and the eigenvalues of a positive definite Hermitian matrix and get inequalities about the trace and eigenvalues between the Schur complement of the sum of positive definite Hermiteian matrix and the sum of the Schur complements of positive definite Hermiteian matrix by proving an inequality.
