摘要 文章研究一类尖层的Dirichlet边值问题.在适当条件下,用伸长变量构造问题的尖层校正项,用合成展开法构造出该问题的形式近似式,应用微分不等式理论证明解的存在性及其渐近性质. Some singularly perturbed semilinear boundary value problems with spike layer properties are studied. Under certain conditions, the formal approximation of the problem is constructed using the method of composite expansions, and the existence and asymptotic behavior of solutions are proved by theory of differential inequalities.
