摘要

SIAM 应用动力系统期刊》，第 23 卷第 3 期，第 1705-1719 页，2024 年 9 月。摘要.2006 年，亚历山大证明了一个结果，即对于魏格登曲面[math]，如果[math]是闭合大地线绕旋转轴旋转的次数，[math]是大地线绕赤道摆动的次数，则当[math]为[math]时，[math]为[math]；当[math]为[math]时，[math]为[math]。在本文中，我们提出了亚历山大对魏格登曲面[math]结果的另一个证明，它更简单、更直接。我们的方法是利用某些不完全积分的尖锐估计来获得允许比率的区间[math]。我们用数值计算了[math]的各种组合的闭合大地线，以说明可能存在的各种模式。

Closed Geodesics on Weingarten Surfaces with [math]

SIAM Journal on Applied Dynamical Systems, Volume 23, Issue 3, Page 1705-1719, September 2024.
Abstract.In 2006, Alexander proved a result that implies for a Weingarten surface [math], if [math] is the number of times a closed geodesic winds around the axis of rotation and [math] is the number of times the geodesic oscillates about the equator, then [math] when [math] and [math] when [math]. In this paper, we present another proof of Alexander’s result for the Weingarten surfaces [math] that is simpler and more direct. Our approach uses sharp estimates of certain improper integrals to obtain the intervals for permissible ratios [math]. We numerically compute a number of closed geodesics for various combinations of [math] to illustrate the variety of patterns that are possible.
