具有收获率的脉冲竞争模型的4个正概周期解

Four Positive Almost Periodic Solutions to an Impulses Competition Systems with Harvesting Terms

  • 摘要: 研究了一类具有时滞和收获率的脉冲Plankton Allelopathy模型的正概周期解. 在一些假设条件下,对其解的先验界的情形进行了细致分析,给出了4种可能情形,得到了此模型存在4个正概周期解,补充和完善了已有的相关结果.

     

    Abstract: The existence of positive almost periodic solutions is discussed for a kind of impulsive Plankton Allelopathy model with delays and harvesting terms. Based on continuous theorem of coincidence degree theory and some analysis technique, the priori bounds of solutions of this system is analyzed in detail, in which there are four possible cases. Some sufficient conditions for the existence of four positive almost periodic solutions of the system are obtained, which complements and perfects the existing relevant results.
