Asymptotic behavior of neutral delay differential equation of euler form with constant impulsive jumps

In this paper, we investigate the asymptotic behavior of solutions for a class of forced nonlinear neutral differential equation in first-order Euler form with constant impulsive jumps and unbounded delay. Several new sufficient conditions are given to guarantee that every non-oscillatory/oscillatory solution of system tends to zero as t→∞. Our conclusions improve and generalize some related existing results in the literatures.
