Sibson’s formula for higher order Voronoi diagrams
(2024)
Conference report
Open AccessLet $S$ be a set of $n$ points in general position in $\mathbb{R}^d$. The order-$k$ Voronoi diagram of $S$, $V_k(S)$, is a subdivision of $\mathbb{R}^d$ into cells whose points have the same $k$ nearest points of $S$. ... -
Properties for Voronoi diagrams of arbitrary order on the sphere
(2022)
Conference report
Open AccessFor a given set of points U on a sphere S, the order k spherical Voronoi diagram SVk(U) decomposes the surface of S into regions whose points have the same k nearest points of U. We study properties for SVk(U), using ... -
An application to measure consensus on customers’ ratings using Hesitant Fuzzy Linguistic Term Sets
(IOS Press, 2023)
Conference lecture
Open AccessIn this study, we propose a methodology using hesitant fuzzy linguistic term sets to aggregate rating values. The main idea is to define an integrated methodology for collaborative platforms involving individuals that use ... -
Cospectral generalized Johnson and Grassmann graphs
(2022)
Conference lecture
Open AccessGraphs with the same spectrum are called cospectral. A graph is determined by its spectrum if every graph cospectral with it is isomorphic to it. We ponder the question "Which graphs are determined by their spectrum?" for ... -
Product-free sets in the free group
(2023)
Conference lecture
Open AccessWe prove that product-free sets of the free group over a finite alphabet have max-imum density1/2with respect to the natural measure that assigns total weight oneto each set of irreducible words of a given length. This ... -
Chordal graphs with bounded tree-width
(Masaryk University, 2023)
Conference lecture
Open AccessGiven $t\ge 2$ and $0\le k\le t$, we prove that the number of labelled $k$-connected chordal graphs with $n$ vertices and tree-width at most $t$ is asymptotically $c n^{-5/2} \gamma^n n!$, as $n\to\infty$, for some constants ... -
On polynomials associated to Voronoi diagrams of point sets and crossing numbers
(Universitat Politècnica de Catalunya (UPC), 2023)
Conference report
Open AccessThree polynomials are defined for sets S of n points in general position in the plane: The Voronoi polynomial with coefficients the numbers of vertices of the order-k Voronoi diagrams of S, the circle polynomial with ... -

Measuring cocircularity in a point set
(2023)
Conference report
Open AccessIn a given set S of n points in the plane, how close are four points of S to be cocircular? We define several measures to study this question, and present bounds on this almost-cocircularity in a point set. Algorithms for ...
