Abstract
This paper is devoted to study the existence of positive solutions for singular second-order periodic boundary value problem with impulse effects. Existence is established via the theory of fixed point theorem in cones.
Keywords: Positive solution, periodic boundary value problem, second-order impulsive differential equations, fixed point theorem
