非极小常中曲率曲面的Björling问题

The Björling problem for non-minimal constant mean curvature surfaces

David Brander, Josef F. Dorfmeister

摘要:

经典的Björling问题是寻找包含给定的实解析曲线的极小曲面,该曲线具有沿曲线指定的切面。我们考虑这个问题的推广到非最小常数中曲率(CMC)的表面,并表明,它可以通过这样的表面的循环组配方解决。主要结果给出了一种直接从Björling数据计算解的全纯势的方法,只使用实解析函数的初等微分、积分和全纯延拓.结合岩泽分解的循环组,这给出了解决方案,在模拟施瓦茨公式的最小情况。一些初步的应用实例的建设CMC表面的特殊性质。

英文摘要:

The classical Björling problem is to find the minimal surface containing a given real analytic curve with tangent planes prescribed along the curve. We consider the generalization of this problem to non-minimal constant mean curvature (CMC) surfaces, and show that it can be solved via the loop group formulation for such surfaces. The main result gives a way to compute the holomorphic potential for the solution directly from the Björling data, using only elementary differentiation, integration and holomorphic extensions of real analytic functions. Combined with an Iwasawa decomposition of the loop group, this gives the solution, in analogue to Schwarz's formula for the minimal case. Some preliminary examples of applications to the construction of CMC surfaces with special properties are given.
