Special Session 59: Central configurations, periodic solutions, variational method and beyond in celestial mechanics
Contents
We generalize the classical Ambrosetti-Rabinowitz's Mountain Pass Lemma
with Palais-Smale condition for C1 functional to some singular case with Cerami-
Palais-Smale condition and then to study the existence of new periodic solutions
with a xed period for the singular second order Hamiltonian systems with Strong
Force Potential.
