Jiemin Zhao · Miskolc mathematical notes/Mathematical notes · 2014
Uniform boundedness and uniform ultimate boundedness of solutions of retarded functional differential equations are studied by Liapunov functions.The obtained result in this work improves Razumikhin theorems on uniform ultimate boundedness.Some examples are given to illustrate the advantage of the obtained result.
