A Lyapunov function for an autonomous dynamical system with an equilibrium point at is a scalar function that is continuous, has continuous first derivatives, is strictly positive for , and for which the time derivative is non positive (these conditions are required on some region containing the origin). The (stronger) condition that is strictly positive for is sometimes stated as is locally positive definite, or is locally negative definite.
