Yuika Kajihara, Mitsuru Shibayama, Guowei Yu

AI总结:

本文研究偏心率趋于1时平面Sitnikov问题的极限情形,利用变分方法证明了在实现非周期符号序列的周期轨道之间存在无穷多个同宿和异宿解。

摘要:

Sitnikov 问题是三体问题的一个特例。已知该系统是混沌的,并已通过符号动力学进行了研究(J. Moser,《动力系统中的稳定与随机运动》,Princeton University Press,1973)。我们研究当大质量粒子的偏心率趋于 1 时 Sitnikov 问题的极限情形。通过变分方法,我们证明了平面 Sitnikov 问题中存在无穷多个同宿和异宿解。在先前的工作中,针对某些周期符号序列,第二作者证明了实现这些序列的周期解的存在性。在本文中,我们证明了在实现某些非周期符号序列的这些周期轨道之间存在同宿和异宿解。

英文摘要:

The Sitnikov problem is a special case of the three-body problem. The system is known to be chaotic and has been studied by symbolic dynamics (J. Moser, Stable and random motions in dynamical systems, Princeton University Press, 1973). We study the limiting case of the Sitnikov problem as the eccentricity of the massive particles tends to 1. By variational method, we show the existence of infinitely many homoclinic and heteroclinic solutions in the planar Sitnikov problem. In a previous work, for certain periodic symbolic sequences, the second author showed the existence of periodic solutions realizing them. In this paper, we show the existence of homoclinic and heteroclinic solutions between some of these periodic orbits which realize certain non-periodic symbolic sequences.
