摘要:

本文针对连续对称群作用使构型空间成为主丛的非完整离散力学系统,提出了一种拉格朗日约化与重构过程。约化过程的结果是一个离散动力系统,我们称之为离散约化系统。通过分析两类离散对称系统,我们展示了该技术的应用,在这两类系统中可以进一步得到确定离散约化系统动力学的(受迫)离散力学系统。

英文摘要:

In this paper we propose a process of lagrangian reduction and reconstruction for nonholonomic discrete mechanical systems where the action of a continuous symmetry group makes the configuration space a principal bundle. The result of the reduction process is a discrete dynamical system that we call the discrete reduced system. We illustrate the techniques by analyzing two types of discrete symmetric systems where it is possible to go further and obtain (forced) discrete mechanical systems that determine the dynamics of the discrete reduced system.
