具有辛结构和对称性的受控哈密顿系统的正则约化

Regular Reduction of Controlled Hamiltonian System with Symplectic Structure and Symmetry

Jerrold E. Marsden, Hong Wang, Zhen-Xing Zhang

摘要:

本文主要研究具有辛结构和对称性的正则受控Hamilton(RCH)系统的正则约化理论,该约化理论是正则受控Hamilton等价条件下哈密顿系统的正则辛约化理论的推广.因此,为了一致描述定义在余切丛和正则约化空间上的RCH系统,我们首先定义了一类辛纤维丛上的RCH系统。然后利用动量映射和相应的约化辛形式引入了具有对称性的正则点和正则轨道可约RCH系统。此外,我们还给出了RCH系统的正则点和正则轨道约化定理,从而解释了对称可约RCH系统的RpCH-等价、RoCH-等价和伴随可约RCH系统的RCH-等价之间的关系.最后,作为应用,我们将刚体和重顶以及它们的内转子分别看作旋转群$\textmd{SO}(3)$和欧氏群$\textmd{SE}(3)$及其推广上的正则点可约RCH系统,并讨论了它们的RCH-等价性.我们还从端口哈密顿系统的辛结构的角度描述了RCH系统和RCH-等价。

英文摘要:

In this paper, our goal is to study the regular reduction theory of regular controlled Hamiltonian (RCH) systems with symplectic structure and symmetry, and this reduction is an extension of regular symplectic reduction theory of Hamiltonian systems under regular controlled Hamiltonian equivalence conditions. Thus, in order to describe uniformly RCH systems defined on a cotangent bundle and on the regular reduced spaces, we first define a kind of RCH systems on a symplectic fiber bundle. Then introduce regular point and regular orbit reducible RCH systems with symmetry by using momentum map and the associated reduced symplectic forms. Moreover, we give regular point and regular orbit reduction theorems for RCH systems to explain the relationships between RpCH-equivalence, RoCH-equivalence for reducible RCH systems with symmetry and RCH-equivalence for associated reduced RCH systems. Finally, as an application we regard rigid body and heavy top as well as them with internal rotors as the regular point reducible RCH systems on the rotation group $\textmd{SO}(3)$ and on the Euclidean group $\textmd{SE}(3)$,as well as on their generalizations, respectively, and discuss their RCH-equivalence. We also describe the RCH system and RCH-equivalence from the viewpoint of port Hamiltonian system with a symplectic structure.
