ABSTRACT
In this paper, some sufficient conditions are established to guarantee the boundedness of all solutions of a specific nonlinear differential equation of fifth order with constant delay. By introducing a Lyapunov functional, we obtain a new result on the boundedness of solutions of a delay differential equation of fifth order.
Keywords: Boundedness, Lyapunov functional, delay differential equations of fifth order.
