研究了一类具有时滞的Lotka-Volterra竞争系统行波解的存在性.应用具有时滞的反应扩散系统行波解存在性理论,将所研究系统行波解存在性的问题转化为寻找该系统的一对上、下解.给出了该系统在无穷远处的渐进衰减行为,完善并改进了同类系统行波解存在性的结论.
The existence of traveling wave solutions for two species Lotka-Volterra competitive system with delays was investigated.Based on the theory of the existence of traveling wave solutions for reactiondiffusion systems with delays,the main problem was transfered to look for a pair of upper and lower solutions for the system.And the asymptotic behavior of the system was given as an attenuated motion tending to the infinity.The study makes up and improves the results of the existence of traveling wave solutions of a class of systems.
