The ostrogradsky method of integration
WebbTypically the Ostrogradsky instability is associated with the equations of motion involv- ing third or higher order time derivatives. In the case of a single eld, there is indeed a direct link between higher order equations of motion and the existence of an unstable, propagating Ostrogradsky mode. Webb20 sep. 2024 · Gauss-Ostrogradsky theorem basically states that you can calculate flow of the vector field through a macroscopic closed surface as an integral of divergence over the volume, confined in that surface.
