Relative Persistent Homology

open access: yesDiscrete & Computational Geometry, 2022
AbstractThe alpha complex efficiently computes persistent homology of a point cloud $$X$$ X in Euclidean space when the dimension $$d$$ d is low. Given a subset $$A$$ A of $$X$$ X , relative Čech persistent homology

Flow estimation solely from image data through persistent homology analysis

open access: yesScientific Reports, 2021
Topological data analysis is an emerging concept of data analysis for characterizing shapes. A state-of-the-art tool in topological data analysis is persistent homology, which is expected to summarize quantified topological and geometric features ...

Persistent homology in graph power filtrations [PDF]

open access: yesRoyal Society Open Science, 2016
The persistence of homological features in simplicial complex representations of big datasets in Rn resulting from Vietoris–Rips or Čech filtrations is commonly used to probe the topological structure of such datasets.

Persistent homology of groups [PDF]

open access: yesJournal of Group Theory, 2011
We introduce and investigate notions of persistent homology for p-groups and for coclass trees of p-groups. Using computer techniques we show that persistent homology provides fairly strong homological invariants for p-groups of order at most 81. The strength of these invariants, and some elementary theoretical properties, suggest that persistent ...

Modeling of persistent homology [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2019
Topological Data Analysis (TDA) is a novel statistical technique, particularly powerful for the analysis of large and high dimensional data sets. Much of TDA is based on the tool of persistent homology, represented visually via persistence diagrams.

Geometric Approaches to Persistent Homology

open access: yesSIAM Journal on Applied Algebra and Geometry, 2022
We introduce several geometric notions, including the width of a homology class, to the theory of persistent homology. These ideas provide geometric interpretations of persistence diagrams. Indeed, we give quantitative and geometric descriptions of the "life span" or "persistence" of a homology class. As a case study, we analyze the power filtration on

Photonic band structure design using persistent homology

open access: yesAPL Photonics, 2021
The machine learning technique of persistent homology classifies complex systems or datasets by computing their topological features over a range of characteristic scales. There is growing interest in applying persistent homology to characterize physical

Weighted persistent homology [PDF]

open access: yesInvolve, a Journal of Mathematics, 2019
We introduce weighted versions of the classical Čech and Vietoris-Rips complexes. We show that a version of the Vietoris-Rips Lemma holds for these weighted complexes and that they enjoy appropriate stability properties. We also give some preliminary applications of these weighted complexes.
