【Abstract】 The paper studys the existence of the solutions for second order impulsive integro-differential equations in Banach space by using fixed point theorems. The results improve the some results obtained by Dajun Guo, Jinli Sun and Yihai Ma. Besides,the results greatly simplify the proof of Jinli Sun and Yihai Ma. Based on our results, there is only need for the contraction conditions, but no need for any monotone condition used by Jinli Sun and Yihai Ma.更多还原
