面向相异函数的有向持续同调理论

A directed persistent homology theory for dissimilarity functions

David Méndez, Rubén J. Sánchez-García

AI总结:

本文提出一种针对有向单纯复形、可检测奇数维持有向环的持续同调理论,建立其与经典持续同调的联系并证明稳定性。

摘要:

我们发展了一种针对有向单纯复形的持续同调理论,可检测奇数维中的持续有向环。我们将有向持续同调与经典持续同调联系起来,证明了若干稳定性结果,并讨论了该方法的计算挑战。该理论由半环系数同调激发:通过显式去除加法逆元,我们能够以代数方式检测有向环。

英文摘要:

We develop a theory of persistent homology for directed simplicial complexes which detects persistent directed cycles in odd dimensions. We relate directed persistent homology to classical persistent homology, prove some stability results, and discuss the computational challenges of our approach. Our directed persistent homology theory is motivated by homology with semiring coefficients: by explicitly removing additive inverses, we are able to detect directed cycles algebraically.
