Abstract
In this paper Hamiltonian system of time dependent periodic Newton equations is studied It is shown that for dimensions 3 and higher the following rigidity results holds true if all the orbits in a neighborhood of infinity are action minimizing then the potential must be constant This gives a generalization of the previous result Bialy and Polterovich Math Res Lett 26695–700 1995 where it was required all the orbits to be minimal As a result we have the following application suppose that for the time1 map of the Hamiltonian flow there exists a neighborhood of infinity which is filled by invariant Lagrangian tori homologous to the zero section Then the potential must be constant Remarkably the statement is false for n=1 case and remains unknown to the author for n=2
