Constant mean curvature surfaces of any positive genus [PDF]

open access: yes, 2023
The paper shows the existence of several new families of noncompact constant mean curvature surfaces: (i) singly punctured surfaces of arbitrary genus g 1, (ii) doubly punctured tori, and (iii) doubly periodic surfaces with Delaunay ...

Superharmonicity of curvatures for surfaces of constant mean curvature [PDF]

open access: yesPacific Journal of Mathematics, 1992
The article deals with the superharmonicity of some curvatures (the scalar curvature \(R\), the Gauss-Kronecker curvature \(K\), the \(\nu\)-th mean curvature \({K}_ \nu\), the level curvature \(L\)) of hypersurfaces of constant mean curvature in \(\mathbb{R}^ n\). For instance, it is proved that for a hypersurface of positive sectional curvatures \(R\)

The PDE describing constant mean curvature surfaces [PDF]

open access: yes, 2001
summary:We give an expository account of a Weierstrass type representation of the non-zero constant mean curvature surfaces in space and discuss the meaning of the representation from the point of view of partial differential ...

Constant mean curvature surfaces with circular boundary in R³

open access: yesAnais da Academia Brasileira de Ciências, 2006
In this work we deal with surfaces immersed in R³ with constant mean curvature and circular boundary. We improve some global estimates for area and volume of such immersions obtained by other authors.

Stability of surfaces with constant mean curvature [PDF]

open access: yesProceedings of the American Mathematical Society, 1989
The notion of stability for surfaces with constant mean curvature H used in this paper is not the appropriate one. It requires the second variation of area to be positive for all compactly supported variations, and not only for those that preserve volume. This is such a strong definition that with it round spheres are not stable [cf. \textit{J.

Constant Mean Curvature Spacelike Surfaces in Lorentzian Warped Products

open access: yesAdvances in Mathematical Physics, 2015
We characterize the spacelike slices of a Lorentzian warped product as the only constant mean curvature spacelike surfaces under suitable geometrical and physical assumptions.

Constant mean curvature one surfaces in hyperbolic 3-space using the Bianchi-Calò method

open access: yesAnais da Academia Brasileira de Ciências, 2002
In this note we present a method for constructing constant mean curvature on surfaces in hyperbolic 3-space in terms of holomorphic data first introduced in Bianchi's Lezioni di Geometria Differenziale of 1927, therefore predating by many years the ...

Delaunay ends of constant mean curvature surfaces [PDF]

open access: yesCompositio Mathematica, 2008
Abstract The generalized Weierstrass representation is used to analyze the asymptotic behavior of a constant mean curvature surface that arises locally from an ordinary differential equation (ODE) with a regular singularity. We prove that a holomorphic perturbation of an ODE that represents a Delaunay surface generates a constant mean

On curvature estimates for constant mean curvature surfaces [PDF]

open access: yes, 2012
In this paper we review four curvature estimates for constant mean curvature surfaces in R-3. They are the Schoen Curvature Estimate, the Choi-Schoen Curvature Estimate, the One-sided Curvature Estimate by Colding and Minicozzi and the Curvature Estimate
