New Periodic Solutions for Some Planar -Body Problems with Newtonian Potentials
arXiv:1311.1382
Abstract
For some planar Newtonian -body problems, we use variational minimization methods to prove the existence of new periodic solutions satisfying that bodies chase each other on a curve, and the other 3 bodies chase each other on another curve. From the definition of the group action in equations , we can find that they are new solutions which are also different from all the examples of Ferrario and Terracini (2004).
