For every fixed, we explicitly construct 1-dimensional families of embedded constrained Willmore tori parametrized by their conformal class with deforming the homogeneous torus of conformal class The variational vector field at is hereby given by a non-trivial zero direction of a penalized Willmore stability operator which we show to coincide with a double point of the corresponding spectral curve. Further, we characterize for , and the family obtained by opening the “smallest” double point on the spectral curve which is heuristically the direction with the smallest increase of Willmore energy at . Indeed we show in Heller and Ndiaye (2021) that these candidates minimize the Willmore energy in their respective conformal class for , and

非矩形约束Willmore最小化器的候选
对于每个 固定后,我们明确构造了由其共形类参数化的嵌入式约束Willmore花托的一维族 和 变形同质圆环 适形阶级 处的变分矢量场 因此,由受罚的Willmore稳定性算子的一个非平凡的零方向给出,我们证明它与相应光谱曲线的双点重合。此外,我们表征, 和 通过打开光谱曲线上的“最小”双点而获得的族,这是启发式地在Willmore能量增加最小的方向 。的确,我们在Heller和Ndiaye(2021)中证明,这些候选物在其各自的保形类中将Willmore的能量最小化,, 和
