【摘要】 本文主要研究一类具连续时滞的慢扩散三种群互助模型.先研究了一般的含时滞的抛物型方程组,利用上下解方法及相应的单调迭代方法,得到该系统存在唯一解及正平衡解,且该平衡解全局渐近稳定,再将结果运用到三种群互助模型上.更多还原

【Abstract】 In this paper, we study a class of slow-diffusion three-species mutual aid model with continuous delay. Firstly, we study the general parabolic equations with time delay. By using the upper and lower solutions and the corresponding monotone iterative method, we obtain the unique solution and positive equilibrium solution of the system, and the global solution of the equilibrium solution is asymptotically stable, and then we apply the results to the three groups of mutual aid model.更多还原
