摘要:

该文讨论脉冲泛函微分方程
$$\left\{\begin{array}{ll}
x,(t)=f(t,xt), t≥ t0,
△x=I_k(t,x(t-)), t=tk,k∈ Z+,
给出了方程零解渐近稳定性和一致渐近稳定性的充分条件,指出这些条件推广或改进了文献[7--9]的相应结论.

关键词: 一致渐近稳定性, 脉冲, Lyapunov泛函

Abstract: In this paper, sufficient conditions are given for impulsive
functional differential asymptotic stability of impulsive
functional differential equation of the form
$$\left\{\begin{array}{ll}
x,(t)=f(t,xt), t≥ t0,
△x=I_k(t,x(t-)), t=tk,k∈ Z+,
and these conditions extend or improve the corresponding ones in [7-9].

Key words: Uniformly asymptotically stable, Impulse, Lyapunov functional
