Die Gewissheit unsicherer Zeitenperturbation of the integrable system. To study perturbed systems special theoretical methods, known as ., have been developed. They are based on the assumption that the solutions of a perturbed system are close to the corresponding solutions of the unperturbed (integrable) system, and one seeks the

Die Gewissheit unsicherer Zeiten preface mappings significantly simplify the study of systems, by reducing the dimension of the system by one, visualizing the orbits on certain sections of phase space, and thus simplifying the formulation of many concepts of dynamical systems. In this chapter we review the traditional methods to c

Die Gewissheit unsicherer Zeitensystems affected by perturbations. The method is based on the Hamilton–Jacobi method for integrating Hamiltonian equations and Jacobi’s theorem recalled in Sect. 1.2.2. As we have seen there the idea of the Hamilton–Jacobi method consists of finding such a canonical change of variables which reduces

https://doi.org/10.1007/978-3-531-92140-2any small time-periodic perturbation splits the separatrices corresponding to stable and unstable manifolds which leads to the onset of chaotic motion due to the exponential divergence of orbits with close initial conditions. This phenomenon creates the zone of phase space in the small vicinity of t

We consider also the dynamics of particles near the separatrix of long–range potential field. These problems are a motion of particle in a periodically–driven Morse potential and the Kepler problem.

Particular example of these system is a one–degree-of-freedom system with a non-monotonic dependence of the frequency of oscillations on action variable. The second problem is a study of systems subjected to non-smooth perturbations. These problem

In this section we study important properties of the stochastic layer, namely, a rescaling invariance of phase space of systems near the saddle points. This property of motion is generic for typical

Actually, a fusion research in early sixties gave a huge impact on the development of Hamiltonian dynamics, particularly, on mapping methods. Since, particles predominantly follow magnetic field lines the determination of their structure is important to

Ungleiche Netzwerke - Vernetzte Ungleichheitic field lines in so-called ergodic and poloidal divertor tokamaks using mappings. We shall study the general structure of magnetic field, chaotic and statistical properties of field lines in ergodic divertor tokamaks. Mappings constitute an important and computationally efficient tool to study magn
