摘要
利用Mawhin重合度定理讨论了一类带Holling功能反应项的变时滞n维Lotka-Volterra竞争模型正周期解的存在性,给出了与变时滞无关的充分条件,改进了现有的结论.
The existence of positive periodic solutions of a class variable delay Lotka-Volterra competition model with Holling functional response was discussed by using Mawhin's coincidence degree theorem,and time varying delay independent sufficient conditions was given,the existing conclusions was improved.
