Multiple periodic solutions of Hamiltonian systems with prescribed energy
Abstract Consider the periodic solutions of autonomous Hamiltonian systems x ˙ = J ∇ H ( x ) on the given compact energy hypersurface Σ = H −1 ( 1 ) . If Σ is convex or star-shaped, there have been
Homoclinic orbits on compact hypersufaces in 293-1293-1293-1, of restricted contact type
AbstractConsider a smooth Hamiltonian system in ℝ2N, $$\dot x = JH'(x)$$ , the energy surface Σ={x/H(x)=H(0)} being compact, and 0 being a hyperbolic equilibrium. We assume, moreover, that Σ∖{0} is
The fixed energy problem for a class of nonconvex singular Hamiltonian systems
