共线三体问题的符号动力学

Symbolic Dynamics of the Collinear Three-Body Problem

Samuel R. Kaplan

摘要:

不以三重碰撞结束的共线三体问题的解通过无限次的二重碰撞。给定三个质量,我们表明,四个几何量产生一个有限的描述行程的二进制碰撞。在最好的情况下,这种描述是半共轭的庞加莱映射的流量。对于其他情况,这些量给出了可能出现的行程的上界和下界。本文的结果除了描述共线三体问题的动力学外,还重新导出了当N > 2时一般N体问题振荡运动的存在性。

英文摘要:

Solutions to the collinear three-body problem which do not end in triple collision pass through an infinite number of binary collisions. Given three masses, we show that four geometric quantities generate a finite description of itineraries of binary collisions. In the best circumstances, this description is semi-conjugate to a Poincare map of the flow. For other cases these quantities give upper and lower bounds on the itineraries which can occur. In addition to describing the dynamics of the collinear three-body problem, the results of this paper rederives the existence of oscillatory motion in the general N-body problem for N > 2.
