通过将有限类型的S2×R中的极小环与调和映射C!有限类型的S2。我们用多项式Killing域重新表述了Pinkall-Sterling的迭代。我们讨论了光谱曲线、光谱数据和等谱集的几何。我们考虑了具有零点的多项式Killing场以及相应的奇异谱曲线、泡沫子和简单因子。研究了任一有限型极小环的等谱集上的可微结构。我们将这一理论应用于由水平圆分片的两参数嵌入极小环族。
We study minimal annuli in S2 × R of finite type by relating them to harmonic maps C ! S2 of finite type. We rephrase an iteration by Pinkall-Sterling in terms of polynomial Killing fields. We discuss spectral curves, spectral data and the geometry of the isospectral set. We consider polynomial Killing fields with zeroes and the corresponding singular spectral curves, bubbletons and simple factors. We investigate the differentiable structure on the isospectral set of any finite type minimal annulus. We apply the theory to a 2-parameter family of embedded minimal annuli foliated by horizontal circles.
