摘要 受保持矩阵一些性质的函数的启发,通过寻求特殊的正交矩阵,研究域上矩阵空间的保持正交性的函数,对域上全矩阵空间、上三角矩阵空间及对称矩阵空间的保持正交性的函数进行具体的刻画。 Inspired by functions preserving some properties of matrices, the orthogonality - preserving function on the matrix spaces over field of characteristic 0 is studied by finding special orthogonal matrices. Functions preserving orthogonality on the spaces of full matrices, upper triangular matrices, and symmetric matrices are characterized, respectively.
