$(k,l)-$对称CMC曲面的谱曲线理论

The spectral curve theory for $(k,l)-$symmetric CMC surfaces

Lynn Heller, Sebastian Heller, Nicholas Schmitt

摘要:

$S^3$中的常平均曲率曲面可以通过其相关的平坦联络族来研究。在环面的情况下,这种方法导致了对所有CMC环面的模空间的深刻理解。对于高亏格的紧CMC曲面,由于其基本群的非交换性质,理论涉及得更多。本文将\cite{Hi, PiSt}中环面和亏格$2$曲面\cite{He3}的谱曲线理论推广到亏格$g=k\cdot l$的$S^3$中的CMC曲面,使$\mathbb Z_{k+1}$和$\mathbb Z_{l+1}$对称性互换.我们确定其相关的家庭的平坦连接通过某些平坦的线丛连接参数化的谱曲线。我们推广了\cite{HeHeSch}中引入的谱数据流,并证明了对于某些初始曲面族,该流的短时存在性。这样,我们得到了各种家庭的新的CMC曲面的高亏格规定的分支点和规定的脐。

英文摘要:

Constant mean curvature surfaces in $S^3$ can be studied via their associated family of flat connections. In the case of tori this approach has led to a deep understanding of the moduli space of all CMC tori. For compact CMC surfaces of higher genus the theory is far more involved due to the non abelian nature of their fundamental group. In this paper we extend the spectral curve theory for tori developed in \cite{Hi, PiSt} and for genus $2$ surfaces \cite{He3} to CMC surfaces in $S^3$ of genus $g=k\cdot l$ with commuting $\mathbb Z_{k+1}$ and $\mathbb Z_{l+1}$ symmetries. We determine their associated family of flat connections via certain flat line bundle connections parametrized by the spectral curve. We generalize the flow on spectral data introduced in \cite{HeHeSch} and prove the short time existence of this flow for certain families of initial surfaces. In this way we obtain various families of new CMC surfaces of higher genus with prescribed branch points and prescribed umbilics.
