- 11.3: Finding Lyapunov Functions
- Lyapunov’s method and the LaSalle invariance principle are very powerful techniques, but the obvious question always arises, "how do I find the Lyapunov function? The unfortunate answer is that given an arbitrary ODE there is no general method to find a Lyapunov function appropriate for a given ODE for the application of these methods.
