Characterizations of minimal hypersurfaces immersed in certain warped products

Extracta Mathematicae, 2019
Our purpose in this paper is to investigate when a complete two-sided hypersurface immersed with constant mean curvature in a Killing warped product Mn ×ρ R, whose Riemannian base Mn has sectional curvature bounded from below and such that the warping ...

A note on η-quasi-umbilical hypersurfaces in almost Hermitian manifolds

Дифференциальная геометрия многообразий фигур, 2023
In the present note, we consider the introduced by Lidia Vasil’evna Stepanova notion of an -quasi-umbilical hypersurface in an almost Her­mitian manifold.

Classification of Möbius minimal and Möbius isotropic hypersurfaces in S⁵

AIMS Mathematics, 2021
In this paper, we will prove that a closed Möbius minimal and Möbius isotropic hypersurface without umbilic points in the unit sphere $ \mathbb{S}^{5} $ is Möbius equivalent to either the torus $ \mathbb{S}^{2}(\frac{1}{\sqrt{2}})\times\mathbb{S}^{2 ...

Stable anisotropic minimal hypersurfaces in $\mathbf {R}^{4}$

Forum of Mathematics, Pi, 2023
We show that a complete, two-sided, stable immersed anisotropic minimal hypersurface in $\mathbf {R}^4$ has intrinsic cubic volume growth, provided the parametric elliptic integral is $C^2$ -close to the area functional.

Simple fibrations in $(1,2)$ -surfaces

Forum of Mathematics, Sigma, 2023
We introduce the notion of a simple fibration in $(1,2)$ -surfaces – that is, a hypersurface inside a certain weighted projective space bundle over a curve such that the general fibre is a minimal surface of general type with $p_g=2$ and

Rigidity of Complete Minimal Submanifolds in Spheres

Frontiers in Physics, 2020
Let M be an n-dimensional complete minimal submanifold in an (n + p)-dimensional sphere 𝕊n+p, and let h be the second fundamental form of M. In this paper, it is shown that M is totally geodesic if the L2 norm of |h| on any geodesic ball of M is of less ...
