复分析与一类Weingarten曲面

Complex analysis and a class of Weingarten surfaces

Robert L. Bryant

摘要:

将复分析应用于常中曲率球面研究的一个想法推广到更广泛的一类球面,即那些满足某种类型的Weingarten关系的球面,即对于某些光滑函数f,H = f(H^2-K),其中H和K分别是平均曲率和高斯曲率。结果是不是新的或已知结果的微小扩展,但方法,它涉及到引入一个不同的共形结构的表面上比一个诱导的第一基本型,是不同的一个使用的霍普夫和需要较少的技术成果从理论的偏微分方程比霍普夫的方法。这是一份1984年早期手稿的德文版。它从未提交出版,尽管它在一些人中流传,并不时在出版的文章中提到。现在提供这份文件是为了方便那些要求得到一份副本的人。除了纠正各种语法或印刷错误和infelicities和增加一些(明确标记)的意见,在介绍结束时,文本是原来的。

英文摘要:

An idea of Hopf's for applying complex analysis to the study of constant mean curvature spheres is generalized to cover a wider class of spheres, namely, those satisfying a Weingarten relation of a certain type, namely H = f(H^2-K) for some smooth function f, where H and K are the mean and Gauss curvatures, respectively. The results are either not new or are minor extensions of known results, but the method, which involves introducing a different conformal structure on the surface than the one induced by the first fundamental form, is different from the one used by Hopf and requires less technical results from the theory of PDE than Hopf's methods. This is a TeXed version of a manuscript dating from early 1984. It was never submitted for publication, though it circulated to some people and has been referred to from time to time in published articles. It is being provided now for the convenience of those who have asked for a copy. Except for the correction of various grammatical or typographical mistakes and infelicities and the addition of some (clearly marked) comments at the end of the introduction, the text is that of the original.
