A note on Razumikhin theorems in uniform ultimate boundedness
Abstract
Uniform boundedness and uniform ultimate boundedness of solutions of
retarded functional di erential 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.
