Abstract:

For a class of nonlinear singularly perturbed differential difference equations, with the method of boundary layer functions, the authors
construct the uniformly valid asymptotic solutions. Because  the deviating factor, confirming boundary layer functions was difficulty, but with the method of splice, the author not only gave the smooth solution's existence proof, but also the remainder estimation was done.

Key words: Singular perturbation, Differential difference equation, Asymptotic solutions
