The Flyspeck Project: A Formal Proof of the Kepler Conjecture

SOLVED:The Kepler problem. The Kepler problem is the model describing planetary motion, it is one of the most important problems studied in the classical mechanics. Consider the most simple question that single planet orbits the sun, ignore the gravitational interaction of the other planets in the solar system, and assume that the sun is fixed at the origin. The Kepler problem can be abstract into such a problem: As shown in the Problem 9.2, Let in the O x y plane, the particle of mass m move du
