Differentiating small-scale subhalo distributions in CDM and WDM models using persistent homology

J Cisewski-Kehe, BT Fasy, W Hellwing, MR Lovell… - Physical Review D, 2022 - APS
The spatial distribution of galaxies at sufficiently small scales will encode information about
the identity of the dark matter. We develop a novel description of the halo distribution using …

Functional limit theorems for the Euler characteristic process in the critical regime

AM Thomas, T Owada - Advances in Applied Probability, 2021 - cambridge.org
This study presents functional limit theorems for the Euler characteristic of Vietoris–Rips
complexes. The points are drawn from a nonhomogeneous Poisson process on, and the …

On the consistency and asymptotic normality of multiparameter persistent Betti numbers

MB Botnan, C Hirsch - Journal of Applied and Computational Topology, 2022 - Springer
The persistent Betti numbers are used in topological data analysis (TDA) to infer the scales
at which topological features appear and disappear in the filtration of a topological space …

Functional central limit theorems for persistent Betti numbers on cylindrical networks

J Krebs, C Hirsch - Scandinavian Journal of Statistics, 2022 - Wiley Online Library
We study functional central limit theorems for persistent Betti numbers obtained from
networks defined on a Poisson point process. The limit is formed in large volumes of …

Statistical learning on measures: an application to persistence diagrams

O Hacquard, G Blanchard, C Levrard - arXiv preprint arXiv:2303.08456, 2023 - arxiv.org
We consider a binary supervised learning classification problem where instead of having
data in a finite-dimensional Euclidean space, we observe measures on a compact space …

A functional central limit theorem for the empirical Ripley's K-function

CAN Biscio, AM Svane - Electronic Journal of Statistics, 2022 - projecteuclid.org
We establish a functional central limit theorem for the empirical Ripley's K-function of Gibbs
point processes and point processes with fast decay of correlations. Our theorem greatly …

Topology-driven goodness-of-fit tests in arbitrary dimensions

P Dłotko, N Hellmer, Ł Stettner, R Topolnicki - Statistics and Computing, 2024 - Springer
This paper adopts a tool from computational topology, the Euler characteristic curve (ECC)
of a sample, to perform one-and two-sample goodness of fit tests. We call our procedure …
