摘要
个体数量动态发展的模型虽然是菲舍儿型的,但是它的个体之间相互竞争项是非局部的.采用数值方法来研究这一模型的平衡解及其相关性质.模型中的影响函数可以取作常数、方块函数以及高斯函数等等,本文考虑的是常数情况.
In this paper, we consider a model for population dynamics which is of the Fisher type but where the competition interaction among individuals is nonlocal. We mainly apply the numerical method to study the equilibrium solutions of the model with some simple influence function such as constant function, square function, Gaussian function and some associated properties. We only consider the constant function in this paper.
