摘要: 研究二阶奇异摄动边值问题,利用重正化群方法, 构造了该边值问题解的一致有效渐近展开式.

关键词: 重正化群方法, 奇异摄动边值问题, 一致有效渐近展式

Abstract: The following singular perturbation boundary value problems are discussed, By using the so called renormalization group method, we give a uniformly valid asymptotic expansions of the boundary value problems under consideration.

Key words: renormalization group method, singular perturbation boundary value problems, uniformly valid asymptotic expansions
