However, if broken trajectories are allowed, the action can sometimes acquire lower values than for any allowed smooth trajectory. Since smooth trajectories are more realistic, leastness has been weakened to stationarity.

Following our earlier conventions, we write this principle as … Webb27 sep. 2015 · The action is sometimes a saddle, but it is a minimum over small enough regions, but the reason it is a minimum instead of a maximum is due to a convention. The action depends on the endpoints, the path and the Lagrangian. So the stationary action (s) and the physical path (s) depend on the endpoints and the Lagrangian. ghurburn harsha neelum

Webb1 sep. 2024 · Is there a deeper proof/ reason behind the Principle of Stationary Action? As the only proof I have seen is showing that, using the Euler Lagrange equations, the Principle will derive Newtons Second Law, and therefore is true experimentally.
