给出了特征不等于2的域F上两个n级对称矩阵一齐合同对角化的充分必要条件;证明了秩为1的两个2级对称矩阵一定可以一齐合同对角化。
This paper gives the sufficient and necessary condition for simultaneously congruent diagonalization of two nxn symmetric matrices over the field F whose characteristic isn't equal to 2 and proves that two 2×2 symmetric matrices with rank 1 can be simultaneously congruent diagonalizable.
