内容简介
《超过KMA理论的哈密顿混沌(国内英文版)》内容简介:Hamiltonian Chaos Beyond the KAM Theory Dedicated to George M. Zaslavsky (1935-2008) covers the recent developments and advances in the theory and application of Hamiltonian chaos in nonlinear Hamiltonian systems. The book is dedicated to Dr. George Zaslavsky who was one of three founders of the theory of Hamiltonian chaos. Each chapter in this book was written by well-established scientists in the field of nonlinear Hamiltonian systems. The development presented in this book goes beyond the KAM theory and the onset and disappearance of chaos in the stochastic and resonant layers of nonlinear Hamiltonian systems are predicted analytically instead of qualitatively.
The book is intended for researchers in the field of nonlinear dynamics in mathematics physics and engineering.

The stochastic web concept dates back to the 1960s when Arnold showed (Arnold,1964) that, in non-degenerate Hamiltonian systems of dimension exceeding 2, reso-nance lines necessarily intersect, forming an infinite-sized web in the Poincar6 sec-tion. It provides in turn for a slow chaotic (sometimes called "stochastic") diffusionfor infinite distances in relevant dynamical variables.
It was discovered towards the end of 1980s (Zaslavsky et al., 1986; Chernikovet al., 1987a,b, 1988) that, in degenerate or nearly-degenerate systems, a stochas-tic web may arise even if the dimension is 3/2. One of the archetypal examples ofsuch a low-dimensional stochastic web arises in the 1D harmonic oscillator per-turbed by a weak traveling wave the frequency of which coincides with a multipleof the natural frequency of the oscillator (Zaslavsky, 2007; Chernikov et al., 1987b;Zaslavsky et al., 1991). Perturbation plays a dual role: on the one hand, it givesrise to a slow dynamics characterized by an auxiliary Hamiltonian that possesses aninfinite web-like separatrix; on the other hand, the perturbation destroys this self-generated separatrix, replacing it by a thin chaotic layer. Such a low-dimensionalstochastic web may be relevant to a variety of physical systems and plays an impor-tant role in corresponding transport phenomena: see (Zaslavsky, 2007; Chernikovet al., 1987b; Zaslavsky et al., 1991) for reviews on relevant classical systems. Inaddition, there are quantum systems in which the dynamics of transport reduces tothat in the classical model described above. The latter concerns e.g. nanometre-scalesemiconductor superlattices with an applied voltage and magnetic fied (Fromholdet al., 2001, 2004).
