摘要
举出一个具有时滞和功能反应的两种群捕食者-食饵扩散系统的反例,并证明该系统不存在正的ω-周期解.这个反例说明了,2003年LI Bin-wen在《Ann.of Diff.Eqs.》上得出的结论是错误的.
In this paper, we give a counterexample on two-species predatorprey Diffusive systems with time delay and functional response and prove that the system does not exist positive-periodic solutions. This counterexample indicates that the result of the paper appeared in 《 Annals of Differential Equations 》 (2003) is incorrect.
