给定一个有限集X和定义在X上的一个适当的度量D:X x X-->R(>=0),我们证明了D的每个块实现都可以典范地“嵌入”到D的紧跨度T(D)中,并将以这种方式得到的T(X)的子集刻画为一个块实现的顶点集的“标准映象”。(C)2008爱思唯尔有限公司。保留所有权利。
Given a finite set X and a proper metric D : X x X --> R(>= 0) defined on X, we show that every block realization of D can be "embedded" canonically into the tight span T(D) of D and characterize the subsets of T(X) that can be obtained in that way as the "canonical image" of the vertex set of a block realization.
