$S^3$中的极小曲面

Minimal surfaces in $S^3$ foliated by circles

N. Kutev, V. Milousheva

摘要:

我们处理单位球面$S^3$中的极小曲面,它是单参数的圆族。极小曲面在$\R^3$叶圆首先由黎曼研究,一百年后劳森建造的例子,这种表面在$S^3$。我们证明了在$S^3$中只有两种类型的极小曲面由圆叶,相交的主线在一个恒定的角度。第一类曲面是由大圆(主线的平分线)所分割的,我们证明了这些极小曲面是著名的Lawson曲面的例子。第二类曲面是一种新的曲面,它是由小圆构成的曲面族,这些小圆是主直线。我们给出了这些曲面的构造公式。给出了$\R^4$中极小叶状半对称超曲面理论的一个应用。

英文摘要:

We deal with minimal surfaces in the unit sphere $S^3$, which are one-parameter families of circles. Minimal surfaces in $\R^3$ foliated by circles were first investigated by Riemann, and a hundred years later Lawson constructed examples of such surfaces in $S^3$. We prove that in $S^3$ there are only two types of minimal surfaces foliated by circles, crossing the principal lines at a constant angle. The first type surfaces are foliated by great circles, which are bisectrices of the principal lines, and we show that these minimal surfaces are the well-known examples of Lawson. The second type surfaces, which are new in the literature, are families of small circles, and the circles are principal lines. We give a constructive formula for these surfaces. An application to the theory of minimal foliated semi-symmetric hypersurfaces in $\R^4$ is given.
