Webpure dynamics. For example, such mappings provide simple models of the motion of charged particles through magnetic lenses and are often used in the study of particle accelerators [1]. Moreover, the quadratic, area preserving map, introduced by H´enon [2], is one of the simplest models of chaotic dynamics. WebSep 2, 2010 · It has been observed that the famous Feigenbaum–Coullet–Tresser period-doubling universality has a counterpart for area-preserving maps of ℝ 2.A renormalization approach has been used in a computer-assisted proof of existence of an area-preserving map with orbits of all binary periods in Eckmann et al [Existence of a fixed point of the …

WebThe dynamics in these real examples is typical for area-preserving maps on surfaces. Aside from the existence of elliptic islands, little is rigorously known about the ergodic theory of such mappings; cf. [Mak1], [Mak2]. Over C. In this paper we will be concerned with the dynamics of automor-phisms of complex K3 surfaces, f : X → X.
WebExercise 8.1. Choose an area-preserving mapping, e.g. the H enon mapping q p 7! 1 q2 + p q or (8.4) for some function f and get a rst impression of the dynamics by numerically drawing a phase portrait. Exercise 8.2. Classify all discrete dynamical systems Z R2! R2 that are de ned by iterating a linear area preserving mapping F: R2! R2. WebThis map was first proposed by Bryan Taylor and then independently obtained by Boris Chirikov to describe the dynamics of magnetic field lines. The standard map and H´enon’s area-preserving quadratic map provide extensively studied paradigms for chaotic Hamiltonian dynamics. The standard map is an exact symplectic map of the cylinder.
WebArea-preserving maps also arise in the study of the motion of Lagrangian tracers in incompressible fluids or of particles tightly gyrating around mag-netic field lines. In …
