On the Moebius deformable hypersurfaces

Abstract

Li, Ma and Wang [Adv. Math. 256 (2014), 156–205] have investigated the interesting class of Moebius deformable hypersurfaces, that is, the umbilic-free Euclidean hypersurfaces $f:M^n\to {\mathbb{R}}^{n+1}$ that admit non-trivial deformations preserving the Moebius metric. The classification of Moebius deformable hypersurfaces of dimension $n\ge 4$ stated in the aforementioned article, however, misses a large class of examples. In this article, we complete that classification for $n\ge 5$.
