On Maximal Homogeneous 3-Geometries and Their Visualization
Universe, 2017 The motivation for this talk and paper is related to the classification of the homogeneous simply connected maximal 3-geometries (the so-called Thurston geometries: E 3 , S 3 , H 3 , S 2 × R , H 2 × R ,

Real projective spaces are nonfibrators
Topology and its Applications, 1999 AbstractFibrators are manifolds which, in context, automatically induce approximate fibrations. This paper sets forth a new method for constructing nonfibrators, by establishing that a closed connected manifold N fails to be a codimension k+1 fibrator provided there exists a homeomorphism h of N×Sk onto itself such that proj·h:N×{point}→N is not a ...

CP2 skyrmions and skyrmion crystals in realistic quantum magnets
Nature Communications, 2023 Magnetic skyrmions are nanoscale topological textures that have been recently observed in different families of quantum magnets. These objects are called CP1 skyrmions because they are built from dipoles—the target manifold is the 1D complex projective ...

On real hypersurfaces in quaternionic projective space with 𝒟⊥-recurrent second fundamental tensor
International Journal of Mathematics and Mathematical Sciences, 1999 In this paper, we give a complete classification of real hypersurfaces in a quaternionic projective space QPm with 𝒟⊥-recurrent second fundamental tensor under certain condition on the orthogonal distribution 𝒟.

Some results on the projective cone normed tensor product spaces over banach algebras
Boletim da Sociedade Paranaense de Matemática, 2018 For two real Banach algebras $\mathbb{A}_1$ and $\mathbb{A}_2$, let $K_p$ be the projective cone in $\mathbb{A}_1\otimes_\gamma \mathbb{A}_2$. Using this we define a cone norm on the algebraic tensor product of two vector spaces over the Banach algebra $\

Mathematics, 2022 Complex-variable chaotic systems (CVCSs) have numerous advantages over real-variable chaotic systems in chaos communication due to their increased unpredictability, confidentiality, and the ease of implementation.

An irreducible Heegaard diagram of the real projective 3-space p3
International Journal of Mathematics and Mathematical Sciences, 2000 We give a genus 3 Heegaard diagram H of the real projective space p3, which has no waves and pairs of complementary handles. So Negami's result that every genus 2 Heegaard diagram of p3 is reducible cannot be extended to Heegaard diagrams of p3 with ...

OPTIMAL LINE PACKINGS FROM FINITE GROUP ACTIONS
Forum of Mathematics, Sigma, 2020 We provide a general program for finding nice arrangements of points in real or complex projective space from transitive actions of finite groups. In many cases, these arrangements are optimal in the sense of maximizing the minimum distance.

Angle-resolved photoelectron spectroscopy in a low-energy electron microscope
Structural Dynamics, 2023 Spectroscopic photoemission microscopy is a well-established method to investigate the electronic structure of surfaces. In modern photoemission microscopes, the electron optics allow imaging of the image plane, momentum plane, or dispersive plane ...

On the Algebraic Geometry of Multiview
FoundationsWe study the multiviews of algebraic space curves X from n pin-hole cameras of a real or complex projective space. We assume the pin-hole centers to be known, i.e., we do not reconstruct them. Our tools are algebro-geometric.
