Title: Double Choreography with Collision to 2N Body Problem


The existence of a double choreography with collisions to 2N Body Problem is shown. I will show an overview of a proof of the existence theorem after giving a brief introduction to N Body Problem with some related topics and a class of periodic solutions: choreography.


- N Body Problem describes the motion of N bodies under the Newtonian law of gravity.
- Choreography is a class of periodic solutions in which N equal masses chase each other along a single closed curve with a common time delay.
- Multiple Choreography is a kind of choreography, but the number of curves is not one. A double choreography to 2N Body Problem has two closed curves which are occupied with N masses for each.
