摘要

我们解决了根据从表面到旋转轴的距离,用任意连续函数在旋转表面上规定不同类型的曲率(主曲率、平均曲率或高斯曲率)的问题。在这条线上,我们得到了平均曲率或高斯曲率与表面到旋转轴的距离成反比的旋转表面的完整显式分类。我们还在一些众所周知的表面上提供了新的独特性结果,例如链状面或旋转环面,以及其他不太为人所知但同样有趣的物理应用,例如聚酯薄膜气球或Flamm的抛物面。

Rotational surfaces with prescribed curvatures
We solve the problem of prescribing different types of curvatures (principal, mean or Gaussian) on rotational surfaces in terms of arbitrary continuous functions depending on the distance from the surface to the axis of revolution. In this line, we get the complete explicit classification of the rotational surfaces with mean or Gauss curvature inversely proportional to the distance from the surface to the axis of revolution. We also provide new uniqueness results on some well known surfaces, such as the catenoid or the torus of revolution, and others less well known but equally interesting for their physical applications, such as the Mylar balloon or the Flamm's paraboloid.
