Abstract

We study the existence problem for tilted unduloids in H2×R\mathbb{H}^2\times\mathbb{R}. These are singly periodic annuli with constant mean curvature H>1/2H>1/2 in H2×R\mathbb{H}^2\times\mathbb{R}, and the periodicity of these surfaces is with respect to a discrete group of translations along a geodesic that is neither vertical nor horizontal in the Riemannian product H2×R\mathbb{H}^2\times\mathbb{R}. Via the Daniel correspondence we are able to reduce this existence problem to a uniqueness problem in the Berger spheres: if a pair of linked horizontal geodesics bounds exactly two embedded minimal annuli (for a fixed orientation of the boundary curves) then tilted unduloids in H2×R\mathbb{H}^2\times\mathbb{R} exist.
