Title: Solutions to boundary-value problems for second-order
       impulsive differential equations at resonance
   
Author: Yu Tian (Beijing Univ., Beijing, China)

Abstract: 
 In this paper, we investigate the existence and uniqueness
 of solutions to  boundary-value problems  for second-order
 impulsive  differential equations at resonance.
 To obtain these results, we apply fixed point methods and
 new differential inequalities.
