摘要
本文研究三种群食物链,其中第三种群是第二种群的捕食者,第二种群是第一种群的捕食者。我们用上下解方法研究具时滞的耦合半线性抛物方程组的动力学行为,给出了解的渐近性质。
In this paper, the three-species food chain is discussed, in which the third
species is the predator of the second one and the second species is the predator of
the first one. The dynamics of coupled systems of semilinear parabolic equations with
time delays are investigated by using the method of upper and lower solutions, and the
asymptotic behavior of the solution is given.
