要:Are there simple and natural ways to find all Keplerian orbits by variational methods? It is considerably well-known that elliptic Keplerian orbits can be characterized as minimizers of some action functional on suitable function spaces. Variational construction for parabolic Keplerian orbits is less well-known, and the case of hyperbolic orbits is virtually unknown. In this talk I will briefly describe related works and outline my variational construction for hyperbolic Keplerian orbits.
