我们考虑分段线性函数的Reeb图的设置,并研究它们之间的距离是稳定的,这意味着在上确界范数相似的函数应该具有相似的Reeb图。我们定义了Reeb图的编辑距离,并证明了它是稳定的和通用的,这意味着它提供了任何其他稳定距离的上限。相反,通过一个具体的结构,我们表明,交织距离和功能性失真距离Reeb图是不普遍的。
We consider the setting of Reeb graphs of piecewise linear functions and study distances between them that are stable, meaning that functions which are similar in the supremum norm ought to have similar Reeb graphs. We define an edit distance for Reeb graphs and prove that it is stable and universal, meaning that it provides an upper bound to any other stable distance. In contrast, via a specific construction, we show that the interleaving distance and the functional distortion distance on Reeb graphs are not universal.
