约束Willmore曲面是Willmore泛函在共形变分下的临界点。如[5]所示,可以将任何共形浸入约束Willmore环面f与紧致黎曼曲面ε相关联,使得f可以根据ε上的代数数据重建。特别有趣的例子约束Willmore环面是环面与常数平均曲率(CMC)在一个3维空间形式。在[11]和[14]中表明,这些环面的谱曲线是超椭圆的。在本文中,我们证明了在温和的条件下,一个受约束的Willmore环面f在三维空间形式是CMC环面,如果它的谱曲线具有CMC谱曲线的结构。
Constrained Willmore surfaces are critical points of the Willmore functional under conformal variations. As shown in [5] one can associate with any conformally immersed constrained Willmore torus f a compact Riemann surface Σ, such that f can be reconstructed in terms of algebraic data on Σ. Particularly interesting examples of constrained Willmore tori are the tori with constant mean curvature (CMC) in a 3-dimensional space form. It is shown in [11] and in [14] that the spectral curves of these tori are hyperelliptic. In this paper we show under mild conditions that a constrained Willmore torus f in S 3 is a CMC torus in a 3-dimensional space form if its spectral curve has the structure of a CMC spectral curve.
