            Figure 2.6.9: (a) Uniform Stability of x e; (b) uniform convergence of x e; (c) uniform
            asymptotic stability of x e ; (d) global uniform asymptotic stability of x e

            3. The origin is a UAS equilibrium point for



            4. The system


              has an equilibrium point x e=0 which is GUAS.

            5. Consider the system



              the origin is then a GES equilibrium point since the solution is given by
