| Abstract: | The paper studies a multi-species delayed stage-structured competitive model.By the continuation theorem of coincidence degree theory,several sets of easily verifiable criteria are derived for the existence of the positive periodic solution.The results generalize a two-species stage-structured competitive model with delays. |
