Equivalence of energy methods in stability theory
arXiv:math/0601465 · doi:10.1063/1.2716201
Abstract
We will prove the equivalence of three methods, the so called energy methods, for establishing the stability of an equilibrium point for a dynamical system. We will illustrate by examples that this result simplifies enormously the amount of computations especially when the stability can not be decided with one of the three methods.
