What Are Some Physically Relevant Higher-Order Lagrangian Systems?

[Omega137]

Hello!

I`m looking for Lagrangian Systems with Lagrangian function containing higher derivatives in t. I would be really happy if someone can tell some higher order Lagrangians with physical relevance.

Thanks, Viktor

Is there about your question that relates specifically to relativity? If not, then you will probably get better answers if we move this question to the Beyond the Standard Model forum.
