Minimal Immersions of Kahler manifolds into Euclidean Spaces [PDF]

, 2003
It is proved here that a minimal isometric immersion of a Kähler-Einstein or homogeneous Kähler-manifold into an Euclidean space must be totally ...

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 ...

New Results on Boas–Bellman-Type Inequalities in Semi-Hilbert Spaces with Applications

Axioms, 2023
In this article, we investigate new findings on Boas–Bellman-type inequalities in semi-Hilbert spaces. These spaces are generated by semi-inner products induced by positive and positive semidefinite operators.

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 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).

The maximal graph Dirichlet problem in semi-Euclidean spaces [PDF]

Communications in Analysis and Geometry, 2012
The maximal graph Dirichlet problem asks whether there exists a spacelike graph, in a semi-Euclidean space, with a given boundary and with mean curvature everywhere zero. We prove the existence of solutions to this problem under certain assumptions on the given boundary.
