Abstract

The paper builds a DPW approach of Willmore surfaces via conformal Gauss maps. As applications, we provide descriptions of minimal surfaces in \({\mathbb {R}}^{n+2}\), isotropic surfaces in \(S^4\) and homogeneous Willmore tori via the loop group method. A new example of a Willmore two-sphere in \(S^6\) without dual surfaces is also presented.

球体中的Willmore曲面:通过共形高斯映射的DPW方法

本文通过保角高斯映射建立了Willmore曲面的DPW方法。作为应用，我们通过环群方法描述了\({\mathbb {R}}^{n+2}\)中的最小曲面、\(S^4\)中的各向同性曲面和均匀Willmore环面。给出了\(S^6\)中无对偶曲面的Willmore双球的一个新例子。

期刊介绍： The first issue of the "Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg" was published in the year 1921. This international mathematical journal has since then provided a forum for significant research contributions. The journal covers all central areas of pure mathematics, such as algebra, complex analysis and geometry, differential geometry and global analysis, graph theory and discrete mathematics, Lie theory, number theory, and algebraic topology.
