Branching Geodesics of the Gromov-Hausdorff Distance

open access: yesAnalysis and Geometry in Metric Spaces, 2022
In this paper, we first evaluate topological distributions of the sets of all doubling spaces, all uniformly disconnected spaces, and all uniformly perfect spaces in the space of all isometry classes of compact metric spaces equipped with the Gromov ...

A cohomology-based Gromov–Hausdorff metric approach for quantifying molecular similarity [PDF]

open access: yesScientific Reports
We introduce a cohomology-based Gromov–Hausdorff ultrametric method to analyze 1-dimensional and higher-dimensional (co)homology groups, focusing on loops, voids, and higher-dimensional cavity structures in simplicial complexes, to address typical ...

Exact topological inference of the resting-state brain networks in twins [PDF]

open access: yesNetwork Neuroscience, 2019
A cycle in a brain network is a subset of a connected component with redundant additional connections. If there are many cycles in a connected component, the connected component is more densely connected.

FPT-Algorithms for Computing Gromov-Hausdorff and Interleaving Distances Between Trees [PDF]

open access: yes, 2019
The Gromov-Hausdorff distance is a natural way to measure the distortion between two metric spaces. However, there has been only limited algorithmic development to compute or approximate this distance.

Structural stability for scalar reaction-diffusion equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
In this paper, we prove the structural stability for a family of scalar reaction-diffusion equations. Our arguments consist of using invariant manifold theorem to reduce the problem to a finite dimension and then, we use the structural stability of Morse–

Distance Measures Based on Metric Information Matrix for Atanassov’s Intuitionistic Fuzzy Sets

open access: yesAxioms, 2023
The metric matrix theory is an important research object of metric measure geometry and it can be used to characterize the geometric structure of a set. For intuitionistic fuzzy sets (IFS), we defined metric information matrices (MIM) of IFS by using the

The continuous limit of large random planar maps [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We discuss scaling limits of random planar maps chosen uniformly over the set of all $2p$-angulations with $n$ faces. This leads to a limiting space called the Brownian map, which is viewed as a random compact metric space.

Chordal Hausdorff Convergence and Quasihyperbolic Distance

open access: yesAnalysis and Geometry in Metric Spaces, 2020
We study Hausdorff convergence (and related topics) in the chordalization of a metric space to better understand pointed Gromov-Hausdorff convergence of quasihyperbolic distances (and other conformal distances).

Gromov–Hausdorff convergence of non-Archimedean fuzzy metric spaces [PDF]

open access: yes, 2015
We introduce the notion of the Gromov–Hausdorff fuzzy distance between two non-Archimedean fuzzy metric spaces (in the sense of Kramosil and Michalek). Basic properties involving convergence and the fuzzy version of the completeness theorem are presented.

Dendrograms of electroencephalograms and their characterization based on metrics [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
Dendrograms obtained from electroencephalograms are studied as maximal prefix codes. A dendrogram defines a distribution on the space of 2-adic integers and represents a partition, up to the set of zero Haar measure, into balls of nonzero radii.
