Abstract: | This article study some qualitative properties of the second order differential operator with periodic conditions, by using the Schauders fixed-point theorem. We obtained the existence of positive periodic solutions of a class of singular second-order damped differential equations. The conclusions in this paper perfect the existed results. |
