关于平面Rips复形及其对应单位圆盘图的分类

On the Classification of Planar-Rips complexes and their corresponding unit disk graphs

Vinay Sipani, Ramesh Kasilingam

AI总结:

本文对可实现为平面点集Vietoris-Rips复形的伪流形与弱伪流形进行单纯同构分类,并同伦分类二维纯闭平面Rips复形,进而刻画一类所有极大团基数相同的单位圆盘图。

摘要:

给定一个度量空间$(X,d)$,$X$在尺度$r>0$下的Vietoris-Rips复形是一个单纯复形,其单形是$X$中所有直径小于$r$的有限子集。在本文中,我们在单纯同构意义下分类了所有能够实现为平面点集Vietoris-Rips复形的$n$维伪流形和弱伪流形。我们进一步在同伦意义下分类了二维、纯的、闭的平面Rips复形。此外,我们探讨了平面Rips复形的遗传性质,并引入了障碍的概念。我们还整合了我们的发现,以描述一类单位圆盘图,其所有极大团具有相同的基数。我们还推导出了平面Rips复形的若干结构和几何性质。

英文摘要:

Given a metric space $(X,d)$, the Vietoris-Rips complex of $X$ at a scale of $r >0$ is a simplicial complex whose simplices are all those finite subsets of $X$ with diameter less than $r$. In this paper, we classify, up to simplicial isomorphism, all $n$-dimensional pseudomanifolds and weak-pseudomanifolds that can be realized as a Vietoris-Rips complex of planar point sets. We further classify two-dimensional, pure, and closed planar-Rips complexes up to homotopy. Additionally, we explore the hereditary properties and introduce the notion of obstructions in planar-Rips complexes. We also consolidate our findings to describe a class of unit disk graphs, having all maximal cliques of same cardinality. Several structural and geometric properties of planar-Rips complexes have also been derived.
