三体问题的欧拉共线位形

Eulerian collinear configuration for 3-body problem

Liang Ding, Juan Manuel Sánchez-Cerritos, Jinlong Wei

摘要:

对于任意给定质量的三体问题$m_1, \,m_2,\,m_3>0$,只存在欧拉共线中心位形和拉格朗日等边三角形中心位形,而对于平面三体问题,本文证明了存在另一个非碰撞轨迹$q$,它不是闭路空间$\overline{Λ_1}$上拉格朗日作用量的变分极小元,也是欧拉共线中心构型。此外,我们不需要对卷绕数$deg(q_i-q_j)\neq0 \,(i\neq j)$的限制条件。

英文摘要:

For 3-body problem with any given masses $m_1, \,m_2,\,m_3>0$, there exist only Eulerian collinear central configuration and Lagrangian equilateral-triangle central configuration, and in this paper, for planar 3-body problem, we prove that there exists another non-collision trajectory $q$, which is not the variational minimizer of the Lagrangian action on the loop space $\overline{Λ_1}$, is also an Eulerian collinear central configuration at any instant. Moreover, we do not need the restriction condition on the winding number $deg(q_i-q_j)\neq0 \,(i\neq j)$.
