The Newtonian 2-body problem is also called the Kepler problem in honor of Johannes Kepler (1571-1630) for his discovery of three laws of planetary motion, based on which Newton deduced in 1687 the celebrated law of universal gravitation. It is widely considered a well-understood problem, as solving it with given initial data and proving Kepler's three laws require nothing more than tools from elementary calculus. In this talk I will present a variational approach which gives us more insights into Keplerian orbits.


Prof. Kuo-Chang Chen is working in the department of mathematics at National Tsing Hua University, Taiwan. He has been the dean of the department of mathematics. His research interests include dynamical systems, celestial mechanics and partial differential equations. He has published in top journals such asAnnals of Mathandwon anumber of academic honors and awards. He is now an editorial board member ofNonlinearityandDiscrete and Continuous Dynamical Systems–Series A.
