This paper studies the existence and multiplicity of positive solutions of a singular boundary value problem for second-order differential systems with impulse effects. By using the upper and lower solutions method and fixed point index arguments criteria of the multiplicity existence and nonexistence of positive solutions with respect to parameters given in the system are established. 1. Introduction In this paper we consider systems of impulsive differential equations of the form u t Xh1 t f u f v ty 0 t e 0 1 if t1 v f ih2 ifg u t v f 0 t e 0 1 tft1 Au i i1 Iu u t1 Au l Nu u t1 1 Av i i1 Iv v i1 Av i i1 Nv v t1 P u 0 a 0 v 0 b 0 u 1 c 0 v 1 d 0 where x p are positive real parameters Au t t1 u t - u ti and Au t t1 uft - u ft- .
