关于自共轭四元数矩阵特征值的一个不等式

An Inequality of Eigenvalues for Self-conjugate Quaternion Matrices

得到了两个自共轭四元数矩阵和特征值的一个不等式 ,并指出和修正了 Horn R.A.和 Johnson C.R.在“矩阵分析”一书中关于

We obtained an inequality of eigenvalues for A+B of two self conjugate quaternion matrices A and B .Also,we corrected an error in a theorem about eigenvalues of Hermit Matrices in the book “Matrices Analysis” written by Hron R.A.and Johnson C.R.
