Ball-preserving mappings of finite ultrametric spaces
摘要:
证明了表示有限超度量空间$X$和$Y$的有根树$T_X$和$T_Y$是同构的当且仅当存在保球双射$F:X\to Y$ .
英文摘要:
It is shown that the rooted trees $T_X$ and $T_Y$ representing finite ultrametric spaces $X$ and $Y$ are isomorphic if and only if there exists a ball-preserving bijection $F:X\to Y$.
