| Abstract: | A two-species ratio-dependent predator-prey model with time delay and impulse is investigated. By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for this system is established. |
| Keywords: | Time delay Periodic solution Topological degree |
