A Brief Account of G.D.Birkhoff’s Problem in the Problem of Three Bodies

The present article gives a historical survery of G.D.Birkhoff’s seventh problem which is an inquiry about the topological structure of the set of definition of the reduced differential equations of motion.Recent advances in the problem and their meaning have been briefly indicated.The classical 3-body problem concerns how the three particles should move under their mutual Newtonian attraction.By a particle we mean a goometrical point endorsed with a constant positive number m which is called mass.Expressed mathematically,the problem appears as to solving of the following system of differential equations:
