摘要
考虑了一类抽象的离散时间反应扩散方程组的行波解的存在性.通过Schauder's不动点理论和比较原理,将波方程组行波解的存在性变为寻找一对上下解,并将结果应用于两类时滞系统.
The existence of traveling wave fronts in temporally discrete reaction-diffusion systems with delays was discussed.By using Schauder's fixed point theorem and comparison principle,the existence of traveling wave fronts of the system were established.In order to to illustrate the results,traveling wave fronts of the delayed competition Lotka-Volterra model and the delayed Gilpin-Ayala model were considered.
