- ItemOpen AccessConvergence of Solutions of Certain Fourth-Order Nonlinear Differential Equations(2007) Ogundare, B. S.; Okecha, G. E.We give sufficient criteria for the existence of convergence of solutions for a certain class of fourth-order nonlinear differential equations using Lyapunov's second method. A complete Lyapunov function is employed in this work which makes the results to include and improve some existing results in literature.
- ItemOpen AccessOn the Boundedness and the Stability of Solution to Third Order Non-Linear Differential Equations(2008) Ogundare, B. S.; Okecha, G. E.In this paper we investigate the global asymptotic stability, boundedness as well as the ultimate boundedness of solutions to a general third order nonlinear differential equation, using complete Lyapunov function.
