摘要
In this paper, we study the existence and multiplicity of positive periodic and subharmonic solutions of second order singular differential equations with impulsive effects. The proof is based on a generalized version of the Poincare-Birkhoff twist theorem due to Ding and the phase plane analysis methods.
