OSCILLATION AND ASYMPTOTIC PROPERTY OF nTH-ORDER IMPULSIVE DIFFERENTIAL EQUATIONS WITH FORCING TERM
带强迫项的n阶脉冲微分方程的振动性与渐近性

This paper presents a lemma to deal with the sign relation between the non-oscillatory solutions with their derived functions for a class of nth-order impulsive differential equations with forcing term. Some criterions about the oscillation and asymptotic property of the solutions to the equations are obtained.Finally two examples are given to illustrate the effectiveness of these criterions.
