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 ...

Network bipartitioning in the anti-communicability Euclidean space

open access: yesAIMS Mathematics, 2021
We define the anti-communicability function for the nodes of a simple graph as the nondiagonal entries of exp (-A). We prove that it induces an embedding of the nodes into a Euclidean space.

On the Decidability of Connectedness Constraints in 2D and 3D Euclidean Spaces [PDF]

open access: yes, 2011
We investigate (quantifier-free) spatial constraint languages with equality, contact and connectedness predicates as well as Boolean operations on regions, interpreted over low-dimensional Euclidean spaces. We show that the complexity of reasoning varies

Evolutes and focal surfaces of framed immersions in the Euclidean space

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2019
We consider a smooth curve with singular points in the Euclidean space. As a smooth curve with singular points, we have introduced a framed curve or a framed immersion. A framed immersion is a smooth curve with a moving frame and the pair is an immersion.

Minimal homogeneous submanifolds in euclidean spaces [PDF]

open access: yes, 2002
We prove that minimal (extrinsically) homogeneous submanifolds of the Euclidean space are totally geodesic. As an application, we obtain that a complex (intrisecally) homogeneous submanifold of a complex Euclidean space must be totally ...

Bertrand and Mannheim curves of framed curves in the3-dimensional Euclidean space

open access: yesTurkish Journal of Mathematics, 2019
A Bertrand curve is a space curve whose principal normal line is the same as the principal normal line of another curve. On the other hand, a Mannheim curve is a space curve whose principal normal line is the same as the binormal line of another curve ...

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.

Characterizations of Euclidean spheres

open access: yesAIMS Mathematics, 2021
We use the tangential component $ \psi ^{T} $ of an immersion of a compact hypersurface of the Euclidean space $ \mathbf{E}^{m+1} $ in finding two characterizations of a sphere.

Using FastMap to Solve Graph Problems in a Euclidean Space

open access: yesInternational Conference on Automated Planning and Scheduling, 2019
It is well known that many graph problems, like the Traveling Salesman Problem, are easier to solve in a Euclidean space. This motivates the idea of quickly preprocessing a given graph by embedding it in a Euclidean space to solve graph problems ...

Sharp Sobolev type embeddings on the entire Euclidean space [PDF]

open access: yes, 2017
A comprehensive approach to Sobolev-type embeddings, involving arbitrary rearrangement- invariant norms on the entire Euclidean space R^n, is offered. In particular, the optimal target space in any such embedding is exhibited.
