Abstract: The authors studied a class of second order impulsive differential equation problems with periodic boundary value. A sufficient conditi on for the existence of a positive solution was obtained with carefully analyzing and evaluating the equation. The arguments are based on the Mawhin’s successive theorem of coincidencedegree theory.

Key words: the second order impulsive differential equations, coincidence degree, periodic solution
