| Abstract: | The permanence of solution of a class delay difference equation is shown：Pn＋1-Pn=-δnPn＋β/1＋Pn-musing a fixed point theorem,show the existence of periodic positive solution of the equation. The results extends corresponding known results in literature and provides more application value. |
