本文研究旋转Willmore曲面的边值问题,其中位置和平均曲率H=0被指定为边界数据。后者是一个自然的数据时,考虑临界点的Willmore功能类的功能,只有在边界上的位置是固定的。对于特定的边界位置,悬链面和Clifford环面的适当部分是显式解。然而,数值实验表明,一个更丰富的分歧图。在本文中,我们验证了分析的期望分歧图的一些性质。此外,我们提出了一种有限元方法,它允许计算临界点的Willmore功能,而不管其稳定性。
Abstract We study a boundary value problem for Willmore surfaces of revolution, where the position and the mean curvature H=0 are prescribed as boundary data. The latter is a natural datum when considering critical points of the Willmore functional in classes of functions where only the position at the boundary is fixed. For specific boundary positions, catenoids and a suitable part of the Clifford torus are explicit solutions. Numerical experiments, however, suggest a much richer bifurcation diagram. In the present paper we verify analytically some properties of the expected bifurcation diagram. Furthermore, we present a finite element method which permits the calculation of critical points of the Willmore functional irrespective of their stability properties.
