Potentials and Impossibility of Oscillations | Nonlinear Dynamics
After a long hiatus from this Nonlinear Dynamics, I have finally returned with a 4th video! In this lesson, I begin with proving that oscillations for a 1-D autonomous dynamical system of the form dx/dt = f(x) are IMPOSSIBLE.
Then, I introduce the concept of potentials of differential equations. Potentials are another useful way of examining a differential equation and are convenient quantities because they behave in a manner similar to potential energies in Physics (i.e. physical systems prefer a state of lower potential energy, similar to how dynamical systems here tend to lower their potential over time).
After introducing potentials, I finish off by solving a quick example problem which shows how potentials can be utilized to ascertain the behaviour of a nonlinear ODE.
