Summary: The problem of constructing the ideal triple: “metric – pilot function – vector field” for a given dynamical system is considered. Properties of the triple are studied, and the notion of the (ideal) Lyapunov function for the given dynamical system is introduced. This notion allows one to construct the Lyapunov function directly by the right-hand side of the given differential equation.
