Colloquium

Is the Solar system stable? — a historical topic revisited

This event is co-sponsored by the GW Confucius Institute

Speaker: Cheng Chong-Qing, Nanjing University
 

Abstract: The system I am going to talk about is an idealized model: to study n mass points which move in 3 dimensional space according to Newton’s law. We assume further that n-1 of these fictions mass points havevery small masses compared to the remaining one, which plays the role of the sun. I shall introduce some ideas to study this problem and give a brief review on new progress in the field.
