常中曲率环面谱数据在$ S ^ 3 $中的封闭性

The Closure of Spectral Data for Constant Mean Curvature Tori in $ S ^ 3 $

Emma Carberry, Martin Ulrich Schmidt

摘要:

sinh-Gordon方程的有限型解的谱曲线对应描述了它们是如何产生和产生具有实结构的超椭圆曲线的。当这些谱曲线满足周期性条件时,$ S ^ 3 $中的常中曲率(CMC)2-环面就产生了。我们证明了CMC环面的谱曲线在sinh-Gordon方程有限型解的光滑谱曲线空间中是稠密的。这样做的一个结果是,对于每个正整数$ n $,在$ S ^ 3 $中存在可数个CMC环面的实$ n $维族.

英文摘要:

The spectral curve correspondence for finite-type solutions of the sinh-Gordon equation describes how they arise from and give rise to hyperelliptic curves with a real structure. Constant mean curvature (CMC) 2-tori in $ S ^ 3 $ result when these spectral curves satisfy periodicity conditions. We prove that the spectral curves of CMC tori are dense in the space of smooth spectral curves of finite-type solutions of the sinh-Gordon equation. One consequence of this is the existence of countably many real $ n $-dimensional families of CMC tori in $ S ^ 3 $ for each positive integer $ n $.
