چکیده
We obtain a $1$-parameter family of horizontal Delaunay surfaces with positive constant mean curvature in $\mathbb{S}^2\times\mathbb{R}$ and $\mathbb{H}^2\times\mathbb{R}$, being the larger than $\frac{1}{2}$ latter case. These are not equivariant but singly periodic, lie at bounded distance from geodesic, complete unduloids previously given by authors. study detail geometry whole show that properly embedded $\mathbb H^2\times\mathbb{R}$. also find (among unduloids) families tori S^2\times\mathbb{R}$ which continuous deformations stack tangent spheres to invariant cylinder. In particular, we first non-equivariant examples $\mathbb{S}^2\times\mathbb{R}$, have $H>\frac12$. Finally, prove there no immersed surface $H\leq\frac{1}{2}$ geodesic $\mathbb{H}^2\times\mathbb{R}$.

Constant mean curvature surfaces with Delaunay ends
In this paper we shall present a construction of Alexandrov-embedded complete surfaces M in R with nitely many ends and nite topology, and with nonzero constant mean curvature (CMC). This construction is parallel to the well-known original construction by Kapouleas [3], but we feel that ours somewhat simpler analytically, and controls the resulting geometry more closely. On the other hand, the ...
متن کاملDelaunay Ends of Constant Mean Curvature Surfaces
We use the generalized Weierstrass representation to analyze the asymptotic behavior of a constant mean curvature surface that locally arises from an ODE with a regular singularity. We show that if system is a perturbation of that of a Delaunay surface, then the corresponding constant mean curvature surface has a properly immersed end that is asymptotically Delaunay. Furthermore, that end is em...
متن کاملNew Constant Mean Curvature Surfaces
We use the DPW construction [5] to present three new classes of immersed CMC cylinders, each of which includes surfaces with umbilics. The first class consists of cylinders with one end asymptotic to a Delaunay surface. The second class presents surfaces with a closed planar geodesic. In the third class each surface has a closed curve of points with a common tangent plane. An appendix, by the t...
متن کاملCoplanar Constant Mean Curvature Surfaces
We consider constant mean curvature surfaces with finite topology, properly embedded in three-space in the sense of Alexandrov. Such surfaces with three ends and genus zero were constructed and completely classified by the authors [GKS2, GKS1]. Here we extend the arguments to the case of an arbitrary number of ends, under the assumption that the asymptotic axes of the ends lie in a common plane...
