摘要
结合次合同、O-合同矩阵等概念,提出新的定义次O-合同。证明了次O-合同是一种等价关系,同时给出了矩阵A、B次O-合同的充分必要条件,然后利用次正交矩阵的性质得到次O-合同矩阵的行列式之间的关系。
In this paper, O- subcongruent of matices was introduced by the concepts of sub- congruent and O- congruent. The fact that O - subcongruent is a kind Of equivalent relation was proved. Meanwhile, this paper also gave some necessary and sufficient conditions for O - subcongruent of matices. Then by the properties of sub - orthogonal matrix ,the relations of their determinant were gained.
