| Abstract: | In this paper, we investigate predator prey model with Holling III functional response governed by difference equations with periodic coefficients. a set of easily verifiable sufficient conditions are derived about the existence of positive periodic solution of system(1.2) by using the method of coincidence degree. |
| Keywords: | Predator prey system Positive periodic solution difference equation Coincidence degree |
