I am looking for a proof of the next theorem:
"If the higher order time derivative Lagrangian is non-degenerate, there is at least one linear instability in the Hamiltonian of this system."
Where Non-degeneracy means that the highest time derivative term can be expressed in terms of canonical variables.
P.S
I prefer a reference, as in a book or article.
