一种新的非碰撞奇点机制

A New Mechanism for Noncollision Singularities

Joseph Gerver, Guan Huang, Jinxin Xue

摘要:

本文在不同于[J. Xue,Acta Math.V224(2)253-388,2020.]的模型下,证明了平面四体问题非碰撞奇点的存在性.在这个模型中,加速度可以任意快,质量可以比较。这一工作为构造非碰撞奇点以及其它相关的复杂动力学轨道提供了一般原则。它不仅回答了[J. Xue,Acta Math.V224(2)253-388,2020]中的一个问题。而且解决了Anosov猜想的类似版本。

英文摘要:

In this paper, we prove the existence of noncollision singularities in a planar four-body problem in a model different from [J. Xue,Acta Math.V224(2)253-388, 2020.]. In this model, the acceleration can be arbitrarily fast and the masses can be comparable. This work provides a general principle to construct noncollision singularities as well as other related orbits with complicited dynamics. It not only answers a question in [J. Xue,Acta Math.V224(2) 253-388, 2020.] but also solves an analogous version of a conjecture of Anosov.
