On Voronoi Diagrams on the Information-Geometric Cauchy Manifolds

open access: yesEntropy, 2020
We study the Voronoi diagrams of a finite set of Cauchy distributions and their dual complexes from the viewpoint of information geometry by considering the Fisher-Rao distance, the Kullback-Leibler divergence, the chi square divergence, and a flat ...

Absolute profinite rigidity and hyperbolic geometry [PDF]

open access: yesAnnals of Mathematics, 2018
We construct arithmetic Kleinian groups that are profinitely rigid in the absolute sense: each is distinguished from all other finitely generated, residually finite groups by its set of finite quotients.

Efficient Shortest Paths in Scale-Free Networks with Underlying Hyperbolic Geometry [PDF]

open access: yesInternational Colloquium on Automata, Languages and Programming, 2018
A standard approach to accelerating shortest path algorithms on networks is the bidirectional search, which explores the graph from the start and the destination, simultaneously.

Hyperbolic Geometry and Neutrosophic Trigonometry: A Unified Approach to Uncertainty Management in Geometric Spaces [PDF]

open access: yesNeutrosophic Sets and Systems
This paper addresses the challenge of modeling uncertainty in hyperbolic geometry, where non Euclidean properties, such as angle sums in triangles smaller than 180°, complicate traditional trigonometric calculations.

Gaplessness of Landau Hamiltonians on Hyperbolic Half-planes via Coarse Geometry [PDF]

open access: yesCommunications in Mathematical Physics, 2020
We use coarse index methods to prove that the Landau Hamiltonian on the hyperbolic half-plane, and even on much more general imperfect half-spaces, has no spectral gaps.

How the latent geometry of a biological network provides information on its dynamics: the case of the gene network of chronic myeloid leukaemia

open access: yesFrontiers in Cell and Developmental Biology, 2023
Background: The concept of the latent geometry of a network that can be represented as a graph has emerged from the classrooms of mathematicians and theoretical physicists to become an indispensable tool for determining the structural and dynamic ...

The Formulas of Möbius-Bretschneider and Möbius-Cagnoli in the Poincaré Disc Model of Hyperbolic Geometry

open access: yesAl-Mustansiriyah Journal of Science, 2021
In this paper, we present two gyroarea formulas (Möbius-Bretschneider’s formula and Möbius-Cagnoli’s formula) for Möbius gyroquadrilaterals in the Poincaré disc model of hyperbolic geometry.

Hyperbolic Geometry [PDF]

open access: yes, 2013
The author considers the space of relativistic velocities in the Minkowski vector space \(\mathbb{R}^{1,n}\) as the unit ball \(B^n \subset \mathbb{R}^n \) with the non-commutative non-associative invertible binary operation \(\oplus\), defined by the relativistic addition of velocities.

The hyperbolic geometry of Markov’s theorem on Diophantine approximation and quadratic forms [PDF]

open access: yesL'Enseignement mathématique, 2017
Markov's theorem classifies the worst irrational numbers with respect to rational approximation and the indefinite binary quadratic forms whose values for integer arguments stay farthest away from zero.
