关于零维多参数持续生存的复杂性

On the complexity of zero-dimensional multiparameter persistence

Jacek Brodzki, Matthew Burfitt, Mariam Pirashvili

摘要:

多参数持久性是持久性同源性的自然扩张,引起了人们的广泛兴趣。然而,有重大的理论障碍,阻止充分发展这一有前途的理论。在本文中,我们认为有趣的特殊情况下,多参数持久性零维,可以被视为一种形式的多参数聚类。特别地,我们考虑了滤子拓扑空间的零维同调的多参数持久模,当它们是零生成的时候。在一定的假设下,我们刻画了这类模,并研究了它们的分解。特别是,我们确定了一个自然类的表示,分解,并可以扩展回形成零维多参数持久性模块。我们对这组表示的研究得出结论,尽管有限制,在这组中仍然有无限多类不可分解的。

英文摘要:

Multiparameter persistence is a natural extension of the well-known persistent homology, which has attracted a lot of interest. However, there are major theoretical obstacles preventing the full development of this promising theory. In this paper we consider the interesting special case of multiparameter persistence in zero dimensions which can be regarded as a form of multiparameter clustering. In particular, we consider the multiparameter persistence modules of the zero-dimensional homology of filtered topological spaces when they are finitely generated. Under certain assumptions, we characterize such modules and study their decompositions. In particular we identify a natural class of representations that decompose and can be extended back to form zero-dimensional multiparameter persistence modules. Our study of this set of representations concludes that despite the restrictions, there are still infinitely many classes of indecomposables in this set.
