Decay of non-oscillatory solutions for a system of neutral differential equations

Helena Samajova, Eva Spanikova, Julio G. Dix

Abstract:
In this article we study the non-oscillatory solutions for a system of neutral functional differential equation. We give sufficient conditions for all non-oscillatory solutions to tend to zero as t approaches infinity. Our results are illustrated with an example.
