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

E3S 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 ...

General Fractional Calculus in Multi-Dimensional Space: Riesz Form

Mathematics, 2023
An extension of the general fractional calculus (GFC) is proposed as a generalization of the Riesz fractional calculus, which was suggested by Marsel Riesz in 1949.

On Involute-Evolute Curve Pair in Semi-Euclidean Space

Turkish Journal of Mathematics and Computer Science, 2021
In this study, a kind of generalized involute and evolute curve pair is considered in 4 dimensional semi Euclidean space with 2 index. The curvatures and the associated Frenet Frame of this kind of generalized involute-evolute curve pair are presented.

Convergence and error estimates for pseudo-polyharmonic div-curl and elastic interpolation on a bounded domain

Journal of Numerical Analysis and Approximation Theory, 2023
This paper establishes convergence rates and error estimates for the pseudo-polyharmonic div-curl and elastic interpolation. This type of interpolation is based on a combination of the divergence and the curl of a multivariate vector field and ...

Osculating curves in 4-dimensional semi-Euclidean space with index 2

Open Mathematics, 2017
In this paper, we give the necessary and sufficient conditions for non-null curves with non-null normals in 4-dimensional Semi-Euclidian space with indeks 2 to be osculating curves.

ON SOME PSEUDOSYMMETRY TYPE HYPERSURFACES OF SEMI-EUCLIDEAN SPACES

Demonstratio Mathematica, 2003
The authors consider hypersurfaces in semi-Euclidean spaces, satisfying different conditions of pseudo-symmetry type. Several results combine different kinds of tensor fields (the curvature tensor field, the Ricci tensor field, the Weyl tensor field, etc).
