Abstract: By using the asymptotic theory, a class of singularly perturbed problems with boundary perturbation is considered. Under the appropriate conditions, the asymptotic solution and the existence conditions of the solution are obtained, and from the result a propagation problem in mural wave is applied.

Key words: Boundary perturbation, Singular perturbation, Solvable conditions, Asymptotic solution
