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
