1) arithmetic distance
算术距离
1.
We discuss the relationship between the arithmetic distance and the distance of A and B,and prove that A-B is cogradient to a diagonal matrix if and only if the distance between A and B equals to their arithmetic distance.
设R是一个交换主理想整环(PID),A,B是两个R上的对称矩阵,讨论了A与B的算术距离与距离的关系,证明了A-B可合同对角化的充要条件是:A与B的距离等于它们的算术距离。

In the geometry of matrices, the points of the associated space are a certain kind of matrices, there is an arithmetic distance of two points in this space, and there is a transfo.
在矩阵几何中,空间中的点是某一类矩阵,两点间存在一种算术距离,还有一个变换群作用在这个空间上,两个不同的点间的算术距离为1或最小时称这两点是粘切的。

In the geometry of matrices, the points of the associated space are a certain kind of matrices, there is an arithmetic distance of two points in this space, and there is a transformation group acting on this space.
在矩阵几何中,空间的点是某一类矩阵,两点间存在一种算术距离,还有一个变换群作用在这个空间上,矩阵几何的基本问题就是用尽可能少的几何不变量来刻画这个矩阵空间的变换群,其答案称为这个矩阵几何基本定理。
