$\mathbb{R}^3$中具有给定高斯曲率的旋转曲面

Rotational surfaces of prescribed Gauss curvature in $\mathbb{R}^3$

Antonio Bueno, Irene Ortiz

摘要:

研究了欧氏空间中高斯曲率作为高斯映射的函数的旋转曲面。通过相平面分析,在对给定函数的适当假设下,推广了常高斯曲率旋转曲面的分类,给出了常高斯曲率旋转曲面不存在的例子,并分析了严格凸图的渐近性质.我们还证明了存在的奇异径向解决方案正交相交的旋转轴。

英文摘要:

We study rotational surfaces in Euclidean 3-space whose Gauss curvature is given as a prescribed function of its Gauss map. By means of a phase plane analysis and under mild assumptions on the prescribed function, we generalize the classification of rotational surfaces of constant Gauss curvature; exhibit examples that cannot exist in the constant Gauss curvature case; and analyze the asymptotic behavior of strictly convex graphs. We also prove the existence of singular radial solutions intersecting orthogonally the axis of rotation.
