High Dimensional Hyperbolic Geometry of Complex Networks

open access: yesMathematics, 2020
High dimensional embeddings of graph data into hyperbolic space have recently been shown to have great value in encoding hierarchical structures, especially in the area of natural language processing, named entity recognition, and machine generation of ...

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 ...

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.

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 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.

Supersymmetry and geometry of hyperbolic monopoles [PDF]

open access: yes, 2015
This thesis studies the geometry of hyperbolic monopoles using supersymmetry in four and six dimensions. On the one hand, we show that starting with a four dimensional supersymmetric Yang-Mills theory provides the necessary information to study the ...

A New Hyperbolic Area Formula of a Hyperbolic Triangle and Its Applications

open access: yesJournal of Mathematics, 2014
We study some characterizations of hyperbolic geometry in the Poincaré disk. We first obtain the hyperbolic area and length formula of Euclidean disk and a circle represented by its Euclidean center and radius.
