摘要
在分布时滞核是强核的条件下,通过线性链技巧(linear chain trick)和几何奇异扰动理论,获得带有非局部时滞2个物种竞争扩散模型行波解的存在性.
Under the condition that the distributed delay kernel is the strong kernel, by the linear chain trick and geometric singular perturbation theory, the existence of travelling wave solutions for the two-species competition-diffusion model with nonlocal delays is obtained.
