| Abstract: | By using a continuation theorem based on coincidence degree theory, sufficient conditions are obtained for the existence of at least two positive periodic solution for a class of discreted predator-prey system with harvesting and monotonic functional response. |
| Keywords: | harvesting monotonic functional response discrete multiple positive periodic solutions coincidence degree |
