Abstract

We classify Willmore hypersurfaces of dimension n ≥ 3 in ‫ޒ‬ n+1 with two distinct principal curvatures under Möbius transformation group of ‫ޒ‬ n+1 .We also characterize conformally flat Willmore hypersurfaces in ‫ޒ‬ n+1 for n ≥ 4 in terms of the hyperelastic curves in two-dimensional real space forms.
