关于$C^0$ -持久同调和树

On $C^0$-persistent homology and trees

Daniel Perez

摘要:

在本文中,我们给出了一个度量结构的树,它正确地识别连接组件的超水平集的$\mathbb{R}$ -值连续函数$f$ $X$,并表明它是可能的检索$H_0$ -持久图从这棵树。本文重新讨论了Schweinhart以前提出的同调维数的概念,并给出了后者在$X$上盒维数方面的一些界限,从而部分回答了同一作者的一个问题.我们证明了一个定量版本的Wasserstein稳定性定理有效的正则足够的$X$和$α$ -Hölder功能和讨论这个理论的一些应用随机场和他们的超水平集的拓扑结构。

英文摘要:

In this paper we give a metric construction of a tree which correctly identifies connected components of superlevel sets of $\mathbb{R}$-valued continuous functions $f$ on $X$ and show that it is possible to retrieve the $H_0$-persistent diagram from this tree. We revisit the notion of homological dimension previously introduced by Schweinhart and give some bounds for the latter in terms of the upper-box dimension of $X$, thereby partially answering a question of the same author. We prove a quantitative version of the Wasserstein stability theorem valid for regular enough $X$ and $α$-Hölder functions and discuss some applications of this theory to random fields and the topology of their superlevel sets.
