Invariant Surfaces under Hyperbolic Translations in Hyperbolic Space

Journal of Applied Mathematics, 2014
We consider hyperbolic rotation (G0), hyperbolic translation (G1), and horocyclic rotation (G2) groups in H3, which is called Minkowski model of hyperbolic space.

Geometry and topology of complex hyperbolic and CR-manifolds

, 1997
We study geometry, topology and deformation spaces of noncompact complex hyperbolic manifolds (geometrically finite, with variable negative curvature), whose properties make them surprisingly different from real hyperbolic manifolds with constant ...

Hyperbolic Unfoldings of Minimal Hypersurfaces

Analysis and Geometry in Metric Spaces, 2018
We study the intrinsic geometry of area minimizing hypersurfaces from a new point of view by relating this subject to quasiconformal geometry. Namely, for any such hypersurface H we define and construct a so-called S-structure.

A History of mathematics and the previous knowledge of teachers as grants for planning a course on geometry ball and hyperbolic

Amazônia, 2014
The aim of this research was to study how the historical development of mathematics, with the backdrop of the evolution of geometry, can assist in the continuing education of mathematics’ teachers.

On the hyperbolic symplectic geometry

Journal of Combinatorial Theory, Series A, 2004
The present article provides a new characterization of the geometry on the points and hyperbolic lines of a non-degenerate symplectic polar space. This characterization is accomplished by studying the family of subspaces obtained when considering the polars of all hyperbolic lines. Let \(\mathbb W_{2n-1}(\mathbb F)\) denote the polar space with respect

Local covariant quantum field theory over spectral geometries

, 2004
A framework which combines ideas from Connes' noncommutative geometry, or spectral geometry, with recent ideas on generally covariant quantum field theory, is proposed in the present work.

Catenoid inspired hyperbolic wormhole geometry

Physics Letters B
We unveil a novel class of traversable wormholes exhibiting exact spherical symmetry, geometrically inspired by the minimal surface structure of a catenoid.

One-Parameter Hyperbolic Spatial Locomotions and Invariants of the Axode

Mathematics, 2023
In this paper, based on the E. Study map, direct appearances were sophisticated for one-parameter hyperbolic dual spherical locomotions and invariants of the axodes.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Feature-enriched hyperbolic network geometry

Physical Review Research
Graph-structured data provide an integrated description of complex systems, encompassing not only the interactions among nodes, but also the intrinsic features that characterize these nodes.
