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

Tai-jun Chen, Matteo Fasiello, Eugene A. Lim, Andrew J. Tolley

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.
