摘要
利用局部坐标系统和边界层函数,讨论了一类多种群生态竞争-捕食非线性奇摄动系统的渐近 性,得出了其任意r阶的渐近估计.
In this paper, by means of a local coordinate system and a boundary layer function, we consider the asymptotic solution for a class of nonlinear singularly perturbed delay systems of multispecies ecological competition-predator delays. The rth-order asymptotic estimate is obtained.
