摘要：
In this paper, we prove the existence of a positive periodic solution for nonlinear differential equation with an indefinite singularity by using Green's function and fixed point theorem in cones. The results are applicable to weak as well as strong singularities. At last, we give one example to show the application of the theorem. Published by Elsevier Ltd.
