带约束的高阶导数理论:驱逐奥斯特罗格拉茨基的幽灵
Higher derivative theories with constraints : Exorcising Ostrogradski's Ghost
摘要:
我们证明了线性不稳定的非退化高阶导数理论,Ostrogradski不稳定性,只能通过增加约束,如果原来的理论的相空间减少。
英文摘要:
We prove that the linear instability in a non-degenerate higher derivative theory, the Ostrogradski instability, can only be removed by the addition of constraints if the original theory's phase space is reduced.
