|Title:||Homoclinic Crossing In Open Systems: Chaos In Periodically Perturbed Monopole Plus Quadrupolelike Potentials.|
|Author:||Letelier, P S|
Motter, A E
|Abstract:||The Melnikov method is applied to periodically perturbed open systems modeled by an inverse-square-law attraction center plus a quadrupolelike term. A compactification approach that regularizes periodic orbits at infinity is introduced. The (modified) Smale-Birkhoff homoclinic theorem is used to study transversal homoclinic intersections. A larger class of open systems with degenerated (nonhyperbolic) unstable periodic orbits after regularization is also briefly considered.|
