Free boundary CMC annuli in spherical and hyperbolic balls

Differential Geometry 2024-03-08 v1

Abstract

We construct, for any HRH\in \mathbb{R}, infinitely many free boundary annuli in geodesic balls of S3\mathbb{S}^3 with constant mean curvature HH and a discrete, non-rotational, symmetry group. Some of these free boundary CMC annuli are actually embedded if H1/3H\geq 1/\sqrt{3}. We also construct embedded, non-rotational, free boundary CMC annuli in geodesic balls of H3\mathbb{H}^3, for all values H>1H>1 of the mean curvature HH.
