【Abstract】 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.更多还原
