具有无穷拓扑的适当嵌入的极小平面域是Riemann极小的例子

Properly embedded minimal planar domains with infinite topology are Riemann minimal examples

William H. Meeks, Joaquin Perez

摘要:

这些注释概述了经典极小曲面理论的最新发展,这些理论对于将R^3中具有无限拓扑(等价地,具有无限个端点)的适当嵌入的极小平面域M分类是必不可少的。米克斯、佩雷斯和罗斯的最后分类结果表明,这样的M必须与黎曼在1860年发现的一个经典例子的位似标度全等。这些例子{ \cal R}_s,0<s< \infty,根据矩形椭圆曲线{\C } / {< 1,t \sqrt{-1} >}上的维尔斯特拉斯{ \cal P}-函数{ \cal P}_t定义,是单周期的,并且与R^3中的每个水平面相交成圆或平行于x轴的线。科林、洛佩兹、罗斯、米克斯和罗森伯格的早期工作证明了平面、悬链面和螺旋面是唯一适当嵌入的亏格为零的具有有限拓扑的极小曲面(等价地,具有有限数目的端点)。由于曲面{ \cal R}_s在s趋于0时收敛于悬链面,在s趋于无穷大时收敛于螺旋面,则R^3中所有适当嵌入的非平面极小平面域的模空间{ \cal M}同胚于闭单位区间[0,1]。

英文摘要:

These notes outline recent developments in classical minimal surface theory that are essential in classifying the properly embedded minimal planar domains M in R^3 with infinite topology (equivalently, with an infinite number of ends). This final classification result by Meeks, Perez, and Ros states that such an M must be congruent to a homothetic scaling of one of the classical examples found by Riemann in 1860. These examples {\cal R}_s, 0<s<\infty, are defined in terms of the Weierstrass {\cal P}-functions {\cal P}_t on the rectangular elliptic curve {\C} / {< 1, t\sqrt{-1}>}, are singly-periodic and intersect each horizontal plane in R^3 in a circle or a line parallel to the x-axis. Earlier work by Collin, Lopez and Ros and Meeks and Rosenberg demonstrate that the plane, the catenoid and the helicoid are the only properly embedded minimal surfaces of genus zero with finite topology (equivalently, with a finite number of ends). Since the surfaces {\cal R}_s converge to a catenoid as s tends to 0 and to a helicoid as s tends to infinity, then the moduli space {\cal M} of all properly embedded, non-planar, minimal planar domains in R^3 is homeomorphic to the closed unit interval [0,1].
