Abstract: |
By using coincidence degree theorem, we obtain a sufficient condition for the existence of positive periodic solutions of a delayed discrete ratio-dependent predator-prey model with monotonic functional responses. |
Key words: predator-prey model positive periodic solutions ratio-dependent monotonic functional responses |
