Curvatures of hypersurfaces

open access: yesLietuvos Matematikos Rinkinys, 2010
In this article we generalize some classical formulas for curvatures of hypersurfaces in the n-dimensional Euclidean space using the homogeneous formulas.

On Total Shear Curvature of Surfaces in E^{n+2}

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018
In the present study we consider surfaces in Euclidean (n+2)-space Eⁿ⁺². Firstly, we introduce some basic concepts of second fundamental form and curvatures of the surfaces in Eⁿ⁺².

Examples of surfaces of constant mean curvature

open access: yesДифференциальная геометрия многообразий фигур, 2019
A surface in E3 is called parallel to the surface M if it consists of the ends of constant length segments, laid on the normals to the surfaces at points of this surface. The tangent planes at the corresponding points will be parallel.

Circulant preconditioners for mean curvature-based image deblurring problem

open access: yesJournal of Algorithms & Computational Technology, 2021
The mean curvature-based image deblurring model is widely used to enhance the quality of the deblurred images. However, the discretization of the associated Euler–Lagrange equations produces a nonlinear ill-conditioned system which affects the ...

Factorable Surfaces in Pseudo-Galilean Space with Prescribed Mean and Gaussian Curvatures

open access: yesJournal of New Theory, 2022
We study the so-called factorable surfaces in the pseudo-Galilean space, the graphs of the product of two functions of one variable. We then classify these surfaces when the mean and Gaussian curvatures are functions of one variable.

The mean curvature measure

open access: yesJournal of the European Mathematical Society, 2012
We assign a measure to an upper semicontinuous function which is subharmonic with respect to the mean curvature operator, so that it agrees with the mean curvature of its graph when the function is smooth. We prove that the measure is weakly continuous with respect to almost everywhere convergence.

Submanifolds with curvature normals of constant length and the Gauss map [PDF]

open access: yes, 2004
We show that a submanifold with curvature normal of constant length has constant principal curvatures under suitable global hypothesis.

Geometric Inequalities for a Submanifold Equipped with Distributions

open access: yesMathematics, 2022
The article introduces invariants of a Riemannian manifold related to the mutual curvature of several pairwise orthogonal subspaces of a tangent bundle. In the case of one-dimensional subspaces, this curvature is equal to half the scalar curvature of the
