摘要：For the classical N-body problem, Maderna-Venturelli [Ann. Math. 2020] proved the existence of hyperbolic motions with any positive energy constant, starting from any configuration and along any noncollision configuration. Their original proof needs the results of the long time behavior of solutions by Chazy 1922 and Marchal-Saari 1976, the Holder estimate for Mane's potential by Maderna 2012, and the weak KAM theory. We will give a new and completely different proof for the above existence of hyperbolic motions.
