In this article the authors study Hamiltonian flows associated to smooth functions R R restricted to energy levels close to critical levels. They assume the existence of a saddle-center equilibrium point in the zero energy level . The Hamiltonian function near is assumed to satisfy Moser's normal form and is assumed to lie in a strictly convex singular subset of . Then for all small, the energy level contains a subset near , diffeomorphic to the closed -ball, which admits a system of transversal sections , called a foliation. is a singular foliation of and contains two periodic orbits and as binding orbits. is the Lyapunoff orbit lying in the center manifold of , has Conley-Zehnder index and spans two rigid planes in . has Conley-Zehnder index and spans a one parameter family of planes in . A rigid cylinder connecting to completes . All regular leaves are transverse to the Hamiltonian vector field. The existence of a homoclinic orbit to in follows from this foliation.

This collection deals with several different topics related to the construction and spectral analysis of Hamiltonians of various systems arising in mathematical physics.
In all these cases I4 can be described by a single parameter e as I = 2* = a(w – ea) that is an integral of motion for the Hamiltonian 1 1 H = #(M: + M%) + * M: + b1p1 + b2p2 ([Ju3] and (KoK])). 5. The remaining case, not usually ...
