Noether invariants for constant mean curvature surfaces in 3-dimensional homogeneous spaces

open access: yes, 2013
We give explicit formulæ for Noether invariants associated to Killing vector fields for the variational problem of minimal and constant mean curvature sur-faces in 3-manifolds.

Saddle towers in Heisenberg space

open access: yes, 2014
We construct most symmetric Saddle towers in Heisenberg space i.e. periodic minimal surfaces that can be seen as the desingularization of vertical planes intersecting equiangularly.

The Construction of Doubly Periodic Minimal Surfaces via Balance Equations

open access: yes, 2009
. Using Traizet’s regeneration method, we prove the existence of many new 3-dimensional families of embedded, doubly periodic minimal surfaces. All these families have a foliation of R3 by vertical planes as a limit.

A Bernstein theorem for complete spacelike constant mean curvature hypersurfaces in Minkowski space

open access: yes, 2007
We obtain a gradient estimate for the Gauss maps from complete spacelike constant mean curvature hypersurfaces in Minkowski space into the hyperbolic space.

© Hindawi Publishing Corp. ON THE MODULI SPACE OF SUPERMINIMAL SURFACES IN SPHERES

open access: yes, 2001
Using a birational correspondence between the twistor space of S2n and projective space, we describe, up to birational equivalence, the moduli space of superminimal surfaces in S2n of degree d as curves of degree d in projective space satisfying a ...

Curvature estimates and stability properties of CMC-submanifolds in space forms

open access: yes, 1999
In this survey paper, we review several results connecting geometric properties (compactness, finiteness of the Morse index, caracterization of stable surfaces) and curvature estimates for constant mean curvature submanifolds in simply-connected space ...

Quadratic Harmonic Morphisms and O-Systems

open access: yes, 1995
We introduce O-systems (Definition 3.1) of orthogonal transformations of R m , and establish 1 \Gamma 1 correspondences both between equivalence classes of Clifford systems and that of O-systems, and between Osystems and orthogonal multiplications of ...

The smoothness of Riemannian submersions with non-negative sectional curvature

open access: yes, 2008
Let M n be a complete, non-compact and C ∞-smooth Riemannian manifold with nonnegative sectional curvature. Suppose that S is a soul of M n given by the fundamental theory of Cheeger and Gromoll, and suppose that Ψ: M n → S is a distance nonincreasing ...
