摘要
研究一类生态模型,证明了在大范围内极限环的存在性,对模型不计捕食者种群间竞争的情形,得到了极限环的唯一性,最后应用摄动理论给出了极限环的渐近结构。
The Lotka-Volterra bionomics model is studied . The existence of limit cycles in the large is proved, and the uniqueness of limit cycles in the case of that the predator species are not competitive is obtained. With perturbation theory , the asymptotic structure of limit is given.
