利用构造Lyapunov泛函方法讨论了一类具有正负系数的非线性脉冲泛函微分方程解的渐近性,给出方程的解趋于一个正常数的充分条件,并举例说明定理条件和结论的可实现性.
In this paper, the asymptotic Property of solutions of nonlinear impulsive functional differential equations with positive and negative coefficients is discussed by using Lyapunov functional. The sufficient conditions are obtained for every solution of equation tending to a constant.Meanwhile the examples ase givern to illustrate the usefulness of the theorem.
