Birkhoff系统的形式不变性(英文)
Form Invariance of Birkhoffian Systems
【摘要】 提出一种新的对称性 ,即Birkhoff方程在无限小变换下保持其形式不变的性质 .给出这种形式不变性的定义与判据 ,研究形式不变性与Noether对称性间的关系 ,并举例说明结果的应用
【Abstract】 The form invariance of Birkhoffian systems is a kind of invariance of the Birkhoffian equations under the infinitesimal transformations. The definition and criteria of the form invariance are given, and the relation between the form invariance and the Noether symmetry is studied.
