1) axiom of distance
距离公理
1.
First we define pseudo hyperbolic distance in the set of selfadjoint and commuting operators in the complex Banach space composed by bounded linear operator in complex Hilbert space whose norm are less than 1, then prove pseudo hyperbolic distance meet the condition of axiom of distance and it is not change about transformation φ__S(·) (where S∈B__H) by means of operator function theory.
在复Hilbert空间上的有界线性算子构成的复Banach空间上,对算子范数小于1的交换自伴算子集定义了伪双曲距离,并且利用算子函数论的方法,证明了在此集合上定义的伪双曲距离满足距离公理且它关于变换φS(·)不变(此处S∈BH)。
2) axioms of the distance formulas
距离公式的公理

Through summarizing and proving,here are some distance formulae from point in to hyperplane.
总结了n维欧氏空间中点(或向量)到超平面(子空间)的距离的几种求法,证明了两个新的点(或向量)到超平面的距离公式,推出了向量到子空间距离的一个公式,利用矩阵广义逆给出了点(或向量)在超平面上的射影公式。
2.
In general, if T is a trace class operator, then T can be represented as an absolutely convergent series which is consisted of rank one operators in U, and \$T\-1=infi=1R\-i-1 T=i=1R\-i,R\-iU,rank\R\-i=1,i=1R\-i-1<$ In addition, we obtain the distance formula from an arbitrary operator to U.
利用该结果 ,得到了算子到 U的距离公
