一类具功能性反应的食饵捕食者两种群时滞扩散模型的极限环存在性

Existence of limit cycle for a kind of twin-species predator-prey diffusion delay model with functional response

关于功能性反应的食饵 捕食者三种群或两种群模型的极限环存在性,前人已有不少工作。作者对类似形式,但变量指数不同的两种群模型,用不同的方法导出同样的结论,证明其极限环存在。

There are a number of publications in the literature concerned with the existence of limit cycle for multispecies predatorprey diffusion delay models. This paper demonstrates the limit cycle existence of a twinspecies system with models similar to that reported, but different in variable's index and derivation method. 
