Abstract

This paper is devoted to studying the existence of single and multiple positive solutions to periodic problems for first-order impulsive differential equations. In addition, we apply our existence theorems to nonlinear periodic problems with singularity at the origin. Our proofs are based on Krasnoselskii fixed-point theorem in cones.
