The authors study a system of functional-differential equations with infinite delay. By using Lyapunov functionals, conditions are given for uniform boundedness and uniform ultimate boundedness. The results are based on the method of finding a bound on the averaged values of the unknown solutions and the application of Jensen's inequality. A comparison with earlier results and nice examples make this paper very interesting.
