摘要运用重合度理论中的连续性定理研究了生态系统视角下两企业竞争与合作模型,得到了该模型存在正周期解的一个充分条件,该结果是对前人研究的有益补充. Using the continuation theorem of coincidence degree theory, we obtain a new sufficient condition of existence of positive periodic solutions to a competition and corporation system of two enterprises based on ecosystem. Our result is a good complement to the earlier publications.
