We construct, for any H ∈ R, infinitely many free boundary annuli in geodesic balls of S3 with constant mean curvature H and a discrete, non-rotational, symmetry group. Some of these free boundary CMC annuli are actually embedded if H ≥ 1/√3. We also construct embedded, non-rotational, free boundary CMC annuli in geodesic balls of H3 , for all values H > 1 of the mean curvature H . 2025-03-04T11:08:51Z 2025-03-04T11:08:51Z 2025-01-06 journal article Cerezo, A., Fernández, I. & Mira, P.
