Strong Stable Manifolds and Uniqueness of Parabolic Rays in the Newtonian $N$ -Body Problem

Putian Yang, Shiqing Zhang

We study uniqueness of parabolic motions in the Newtonian $N$ -body problem using strong stable manifolds and direct action comparisons. Fix a minimal normalized central configurati…

Stability of geodesic-ray data, horofunctions, and rectifiability of fixed-shape slices in the Newtonian $N$-body problem

Putian Yang, Shiqing Zhang

For the Newtonian $N$-body problem at nonnegative energy, we study solution sets selected by the Jacobi--Maupertuis variational principle and by the associated stationary Hamilto…
