Abstract

In this paper, a class of nonlinear and nonautonomous neutral functional differential equations is considered. By developing a new integral inequality, we obtain sufficient conditions for the existence of a global attracting set of neutral functional differential equations with time-varying delays. The results have extended and improved the related reports in the literature.

Highlights

  • The asymptotic properties of neutral functional differential equations have attracted considerable attention in the past few decades, and many significant results have been obtained [ – ]

  • One of the most popular ways to analyze the stability property and asymptotic behavior is the method of Lyapunov functionals [ – ]

  • Motivated by the above discussions, in this paper, we will improve the inequality established in [ ] so that it is effective for neutral functional differential equations

Summary

Introduction

1 Introduction The asymptotic properties of neutral functional differential equations have attracted considerable attention in the past few decades, and many significant results have been obtained [ – ]. It seems to work well for constant delays in neutral equations [ , ]. The known approach to the study of differential inequalities for nonautonomous neutral functional differential equations was presented in Azbelev’s book [ ].
