Systems of Transversal Sections near Critical Energy Levels of Hamiltonian Systems in ℝ⁴

Abstract: In this article we study Hamiltonian flows associated to smooth functions H : R 4 → R restricted to energy levels close to critical levels. We assume the existence of a saddle-center equilibrium point pc in the zero energy level H −1 (0). The Hamiltonian function near pc is assumed to satisfy Moser's normal form and pc is assumed to lie in a strictly convex singular subset S 0 of H −1 (0). Then for all E > 0 small, the energy level H −1 (E) contains a subset S E near S 0 , diffeomorphic to the closed 3-ball, w… Show more

“…By considering a subsequence, that we still denote by {u j }, we can also assume that there exist T 5) and in the last limit the convergence is uniform on bounded intervals. This follows from (2.3) which implies that the sequence {u j } is equi-bounded and from (2.2) which implies 6) so that the sequence is also equi-continuous. By passing to a further subsequence we can also assume that u j u…”
