A New Mechanism for Noncollision Singularities
Abstract
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.
