摘要:

给定纤维丛上的有限阶拉格朗日量L,考虑其依赖于动力变量高阶导数的整体广义对称性。得到了第一变分公式。由此导出了相应的拉格朗日守恒律和L的广义对称性的特征方程。

英文摘要:

Given a finite order Lagrangian L on a fibre bundle, its global generalized symmetries depending on higher order derivatives of dynamic variables are considered. The first variational formula is obtained. It leads both to the corresponding Lagarngian conservation laws and the characteristic equation for generalized symmetries of L.
