关于快慢Hamilton系统规范形的整体结构

On the Global Structure of Normal Forms for Slow-Fast Hamiltonian Systems

M. Avendaño Camacho Yu. Vorobiev

摘要:

在Lie变换和整体平均方法的框架下,研究了当未扰动(快)系统的流是周期流且诱导的S^1作用不一定是自由和平凡的情况下,多维快慢Hamilton系统的规范形.根据与周期流相关联的Hannay-Berry联络,导出了一阶S^1不变标准形中第二项的内禀分裂。

英文摘要:

In the framework of Lie transform and the global method of averaging, the normal forms of a multidimensional slow-fast Hamiltonian system are studied in the case when the flow of the unperturbed (fast) system is periodic and the induced S^1-action is not necessarily free and trivial. An intrinsic splitting of the second term in a S^1-invariant normal form of first order is derived in terms of the Hannay-Berry connection associated with the periodic flow.
