摘要
在退化方程f(t,u)u′+g(t,u)=0的解是局部强稳定的等条件下,研究了一般的二阶非线性奇摄动问题的边界层现象.利用界定函数法和微分不等式理论证明了解的存在性,给出了解的渐近估计.
In this paper, the boundary layer behavior of singularly perturbed nonlinear equation with a locally strongly stable reduce solution is considered. estimate of solution are discussed by using the bounding functions method inequality. problem for the second-order The existence and asymptotic and the theory of differential
