【Abstract】 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.
