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 ...

Hausdorff Measures on Generalized Set Valued Neutrosophic Quadruple Numbers and Decision Making Applications for Adequacy of Online Education [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
In this paper, we develop a new method of decision-making algorithm with Hausdorff distance and Hausdorff similarity measures based on generalized set-valued neutrosophic quadruple numbers.

On intersections of Cantor sets: Hausdorff measure [PDF]

open access: yesOpuscula Mathematica, 2013
We establish formulas for bounds on the Haudorff measure of the intersection of certain Cantor sets with their translates. As a consequence we obtain a formula for the Hausdorff dimensions of these intersections.

The Second Generalization of the Hausdorff Dimension Theorem for Random Fractals

open access: yesMathematics, 2022
In this paper, we present a second partial solution for the problem of cardinality calculation of the set of fractals for its subcategory of the random virtual ones.

A Generalization of the Hausdorff Dimension Theorem for Deterministic Fractals

open access: yesMathematics, 2021
How many fractals exist in nature or the virtual world? In this paper, we partially answer the second question using Mandelbrot’s fundamental definition of fractals and their quantities of the Hausdorff dimension and Lebesgue measure.

Determining the Hausdorff Distance Between Trees in Polynomial Time [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
The Hausdorff distance is a relatively new measure of similarity of graphs. The notion of the Hausdorff distance considers a special kind of a common subgraph of the compared graphs and depends on the structural properties outside of the common subgraph.

On the usage of average Hausdorff distance for segmentation performance assessment: hidden error when used for ranking

open access: yesEuropean Radiology Experimental, 2021
Average Hausdorff distance is a widely used performance measure to calculate the distance between two point sets. In medical image segmentation, it is used to compare ground truth images with segmentations allowing their ranking.

On the vectorial multifractal analysis in a metric space

open access: yesAIMS Mathematics, 2023
Multifractal analysis is typically used to describe objects possessing some type of scale invariance. During the last few decades, multifractal analysis has shown results of outstanding significance in theory and applications. In particular, it is widely

A Hausdorff Measure Inequality [PDF]

open access: yesTransactions of the American Mathematical Society, 1976
We prove that the Hausdorff ( m + k ) (m + k) -measure of a product set is no less than the product of the Hausdorff m-measure of the (measurable) first component set in R m {{\mathbf {R}}^m} and the ...
