摘要:

我们探讨了一种特殊的方法来分析的动力学和几何性质的自治,Pfronan非完整系统在经典力学。该方法是基于一定的辅助约束哈密顿系统的建设,其中包括非完整力学系统作为一个不变流形上的动力子系统。嵌入系统在辛几何的背景下具有完全自然的结构,并且使用它来理解子系统的性质具有令人信服的优势。利用Conley-Zehnder理论和Morse-Witten复形之间的相互关系,讨论了嵌入系统和物理系统的临界集的一般几何和拓扑性质.此外,我们给出了在临界集附近的运动稳定性的定性讨论。我们指出的关键关系,子黎曼几何,和一个潜在的计算应用。

英文摘要:

We explore a particular approach to the analysis of dynamical and geometrical properties of autonomous, Pfaffian non-holonomic systems in classical mechanics. The method is based on the construction of a certain auxiliary constrained Hamiltonian system, which comprises the non-holonomic mechanical system as a dynamical subsystem on an invariant manifold. The embedding system possesses a completely natural structure in the context of symplectic geometry, and using it in order to understand properties of the subsystem has compelling advantages. We discuss generic geometric and topological properties of the critical sets of both embedding and physical system, using Conley-Zehnder theory and by relating the Morse-Witten complexes of the 'free' and constrained system to one another. Furthermore, we give a qualitative discussion of the stability of motion in the vicinity of the critical set. We point out key relations to sub-Riemannian geometry, and a potential computational application.
