摘要
研究离散Lagrange系统的Lie对称性.根据离散变分原理建立离散系统的运动方程.给出离散运动方程Lie对称性的定义和确定方程.举例说明结果的应用.
This paper studies the Lie symmetries of discrete Lagrange systems. Based on discrete variational principle, the equations of motion for the discrete systems are established. Definition of Lie symmetry and determining equations for the discrete equations of motion are given. An example is presented to illustrate the application of the results.
