| Abstract: | This paper studies the existence of positive periodic solutions to a class of predator-prey system. Using the coincidence degree theory,we obtain a new result on the existence of positive periodic solutions for the system. The conditions of our theory are more simple than that of the current result,and are easily verified and applied. |
