WebLyapunov theory is used to make conclusions about trajectories of a system x˙ = f(x) (e.g., G.A.S.) without ﬁnding the trajectories (i.e., solving the diﬀerential equation) a typical Lyapunov theorem has the form: • if there exists a function V : Rn → R that satisﬁes some conditions on V and V˙ Webcorresponding linearized system: A= 0 1 0 0 This matrix has two eigenvalues in the origin and therefore the reduced Lyapunov criterion cannot be used. Let us now consider the Lyapunov function V(x) = x4 1 +2x2 2. Computing the derivatives along the trajectories of the nonlinear systems, one obtains: V˙ = −4x6 1 −4x 4 2 < 0, V˙ = 4x6 1 +4x ...

Various types of stability may be discussed for the solutions of differential equations or difference equations describing dynamical systems. The most important type is that concerning the stability of solutions near to a point of equilibrium. This may be discussed by the theory of Aleksandr Lyapunov. In simple terms, if the solutions that start out near an equilibrium point stay near f… Web13 Lyapunov functions 13.1 De nition and main theorem Up till now, for a general system x_ = f(x), x(t) ∈ R2 (1) we have two methods to get insight about the structure of the phase portrait. First, we can study stability of an equilibrium using linearization of (1) around this equilibrium. Second, we can draw the nullclines to infer some ...

This is by no means a proof. Here, however, I am able to prove at least some part of the linearization theorem using a carefully chosen Lyapunov function. First I will need some auxiliary linear algebra facts. matthew dickson obituary
