Variational approach to second species periodic solutions of Poincaré of the 3 body problem

Sergey Bolotin, Piero Negrini

We consider the plane 3 body problem with 2 of the masses small. Periodic solutions with near collisions of small bodies were named by Poincaré second species periodic solutions. S…

Platonic Polyhedra, Topological Constraints and Periodic Solutions of the Classical $N$ -Body Problem

G. Fusco, G. F. Gronchi, P. Negrini

We prove the existence of a number of smooth periodic motions $u_{*}$ of the classical Newtonian $N$ -body problem which, up to a relabeling of the $N$ particles, are invariant under…
