Framed slant helices in Euclidean 3-space [PDF]

open access: goldAdvances in Difference Equations, 2021
In this paper, we define framed slant helices and give a necessary and sufficient condition for them in three-dimensional Euclidean space. Then, we introduce the spherical images of a framed curve.

A Union of Euclidean Metric Spaces is Euclidean [PDF]

open access: yesDiscrete Analysis, 2016
A Union of Euclidean Metric Spaces is Euclidean, Discrete Analysis 2016:14, 15pp. A major theme in metric geometry concerns conditions under which it is possible to embed one metric space into another with small distortion. More precisely, if $M_1$ and $

Characterizations of Framed Curves in Four-Dimensional Euclidean Space

open access: yesUniversal Journal of Mathematics and Applications, 2021
Framed curves in Euclidean space are used to investigate singular curves and are important for singularity theory. In this study, framed curves in four-dimensional Euclidean space are introduced and new results are obtained. The relation of framed curves

Twisted Hypersurfaces in Euclidean 5-Space

open access: yesMathematics, 2023
The twisted hypersurfaces x with the (0,0,0,0,1) rotating axis in five-dimensional Euclidean space E5 is considered. The fundamental forms, the Gauss map, and the shape operator of x are calculated.

Transformation of Non-Euclidean Space to Euclidean Space for Efficient Learning of Singular Vectors

open access: yesIEEE Access, 2020
Singular value decomposition (SVD) is a popular technique to extract essential information by reducing the dimension of a feature set. SVD is able to analyze a vast matrix in spite of a relatively low computational cost.

Specific Emitter Identification Based on Ensemble Neural Network and Signal Graph

open access: yesApplied Sciences, 2022
Specific emitter identification (SEI) is a technology for extracting fingerprint features from a signal and identifying the emitter. In this paper, the author proposes an SEI method based on ensemble neural networks (ENN) and signal graphs, with the ...

Reflection-Like Maps in High-Dimensional Euclidean Space

open access: yesMathematics, 2020
In this paper, we introduce reflection-like maps in n-dimensional Euclidean spaces, which are affinely conjugated to θ : ( x 1 , x 2 , … , x n ) → 1 x 1 , x 2 x 1 , … , x n x 1 .

Path Integrals on Euclidean Space Forms [PDF]

open access: yes, 2015
In this paper we develop a quantization method for flat compact manifolds based on path integrals. In this method the Hilbert space of holomorphic functions in the complexification of the manifold is used. This space is a reproducing kernel Hilbert space.

Features of the geometry of the five-dimensional pseudo-Euclidean space of index two [PDF]

open access: yesE3S Web of Conferences
The article is devoted to the study of the geometry of subspaces of a five-dimensional pseudo-Euclidean space. This space is attractive because all kinds of semi-Euclidean, semi-pseudo-Euclidean, hyperbolic three-dimensional spaces with projective ...
