欧氏空间E3中唯一极小的旋转曲面是悬链面,这是一个经典的结果。当然,曲面是共形平坦的,但如果Mn,n ≠ 4,是欧氏空间En+1的共形平坦超曲面,则Mn有一个特殊的方向[2](“与子午线相切”)。因此,我们寻求特征共形平坦的超曲面的En+1是最小的。具体来说,我们证明了以下定理。设Mn,n ≠ 4,是浸入En+1的共形平坦极小超曲面.
It is a classical result that the only surface of revolution in Euclidean space E3 which is minimal is the catenoid. Of course the surface is conformally flat, but if Mn , n ≧ 4, is a conformally flat hypersurface of Euclidean space En+1, then Mn admits a distinguished direction [2] (“tangent to the meridians“). Thus we seek to characterize conformally flat hypersurfaces of En+1 which are minimal. Specifically we prove the following THEOREM. Let Mn, n ≧ 4, be a conformally flat, minimal hypersurface immersed in En+1.
