| Abstract: | In this paper, we study a class of delay predator-prey systems of two species with harvesting rate and ratio-dependence. By applying Mawhin's continuation theorem of coincidence degree theory, we establish a set of easily verifiable suffficient conditions under which this system has at least two positive periodic solutions. |
| Keywords: | predator-prey system harvesting rate multiple positive periodic solutions coincidence degree |
