| Abstract: |
| In this paper, we study the Willmore hypersurface in space form. Starting from the 2-type rotational hypersurface, by calculating the first fundamental form and the second fundamental form of the 2-type rotational hypersurface, using the method of moving frame, we obtain the equivalent condition that the hypersurface is a minimal Willmore hypersurface, and construct a new example of a minimal Willmore rotational hypersurface with three different principal curvatures in space form. |
