Superintegrability on Three-Dimensional Riemannian and Relativistic Spaces of Constant Curvature
Symmetry, Integrability and Geometry: Methods and Applications, 2006 A family of classical superintegrable Hamiltonians, depending on an arbitrary radial function, which are defined on the 3D spherical, Euclidean and hyperbolic spaces as well as on the (2+1)D anti-de Sitter, Minkowskian and de Sitter spacetimes is ...

On correlation of hyperbolic volumes of fullerenes with their properties
Computational and Mathematical Biophysics, 2020 We observe that fullerene graphs are one-skeletons of polyhedra, which can be realized with all dihedral angles equal to π /2 in a hyperbolic 3-dimensional space. One of the most important invariants of such a polyhedron is its volume.

Physical Review Letters, 2018 A model of cosmological inflation is proposed in which field space is a hyperbolic plane. The inflaton never slow-rolls, and instead orbits the bottom of the potential, buoyed by a centrifugal force. Though initial velocities redshift away during inflation, in negatively curved spaces angular momentum naturally starts exponentially large and remains ...

Creation a New Mathematics Relations Using Engineering Approaches
Journal of Engineering and Sustainable Development, 2009 The mathematics laws, relations and functions are the guide for all the engineering designs and applications. This guide will simplified the work in the design phase but it capture the design in some times because the conditions of high accuracy in ...

Teaching and Learning Hyperbolic Functions (I); Definitions and Fundamental Properties [PDF]
PedActa, 2016 We propose that in some papers (4 maybe 5 !) to present a model of teaching and learning in secondary education of hyperbolic functions, giving many properties (starting with fundamental ones and finishing with development in Tayler ...

Arthritis Care &Research, EarlyView.Objective Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race and ethnicity and household income are associated with severe AAV disease and renal outcomes among

Conjugacy and subgroups of word-hyperbolic groups [PDF]
This thesis describes a number of algorithms and properties relating to Gromov’s word-hyperbolic groups. A fuller outline of the thesis is given, and a number of basic concepts relating to metric spaces, hyperbolicity and automaticity are first ...
