四阶差分方程的不变性和守恒律
The Invariance and Conservation Laws of fourth-order Difference Equations
摘要：
我们考虑四阶差分方程，并确定一个参数李群的变换（李对称），让他们不变。我们介绍了一种技术，找到他们的首次积分，并讨论之间的关联的对称性和首次积分以及乘数的概念（相关的守恒律）的差分方程。
英文摘要：
We consider difference equations of order four and determine the one parameter Lie group of transformations (Lie symmetries) that leave them invariant. We introduce a technique for finding their first integrals and discuss the association between the symmetries and first integrals as well as the notion of multipliers (related to conservation laws) for difference equations.
