We investigate straight-line orbits (SLO) in Hamiltonian force fields using both direct and inverse methods. A general theorem is proven for natural Hamiltonians quadratic in the momenta for arbitrary dimensions and is considered in more detail for two and three dimensions. Next we specialize to homogeneous potentials and their superpositions, including the familiar Hénon–Heiles problem. It is shown that SLO’s can exist for arbitrary finite superpositions of N-forms. The results are applied to… 

Unstable Brake Orbits in Symmetric Hamiltonian Systems

In this thesis we investigate the existence and stability of periodic solutions of Hamiltonian systems with a discrete symmetry. The global existence of periodic motions can be proven using the

Escapes in Hamiltonian systems with multiple exit channels: part I

The aim of this work was to review and also explore even further the escape properties of orbits in a dynamical system of a two-dimensional perturbed harmonic oscillator, which is a characteristic

Non-integrability of the equal mass n-body problem with non-zero angular momentum

We prove an integrability criterion and a partial integrability criterion for homogeneous potentials of degree −1 which are invariant by rotation. We then apply it to the proof of the meromorphic

The Planar Inverse Problem of Dynamics

We consider the following version of the inverse problem of Dynamics: given a monoparametric family of planar curves, find the force field, conservative or not, which determines a material point to

We identify a given two-parametric family of regular orbits given in the form f(x, y, z) = c 1 , g(x, y, z) = c 2 in the 3-D Cartesian space by two functions α (x, y, z) and β(x, y, z) including
