论文摘要

Z.E. Musielak在2008年报道了J. Phys。答:数学。理论。 {\ bf 41} 055205获取标准和非标准拉格朗日的方法,并确定允许拉格朗日描述的运动方程式。在此评论中,我们展示了如何使用以前发现的非标准的Lagrangians获得新的非标准Lagrangians。特别是,对于每个非标准的拉格朗日人都可以生成与新运动方程相关的新的非标准拉格朗日。

Z.E. Musielak has reported in 2008 J. Phys. A: Math. Theor. {\bf 41} 055205 methods to obtain standard and non-standard Lagrangians and identify classes of equations of motion that admit a Lagrangian description. In this comment we show how to obtain new non-standard Lagrangians using the non-standard Lagrangians previously found. In particular, it is demonstrated that for every non-standard Lagrangian one can generate a new non-standard Lagrangian associated to a new equation of motion.
