On Noether Symmetry, Lie Symmetry and Form Invariance
-
摘要: 力学系统的Noether对称性、Lie对称性与形式不变性是3种不同的不变性，它们之间的关系可用3个交叉的圈表示。Abstract: The Noether symmetry, Lie symmetry and form invariance of mechanical systems are three different invariances. The relations among these symmetries can be expressed by three circles intersected each other.
