| Abstract: | The singularly perturbed nonlinear boundary value problems are considered.Using the stretched variable and the method of boundary layer correction,the formal asymptotic expansion of solution is obtained.And then the uniform validity of solution is proved by using the differential inequalities. |
| Keywords: | Singular perturbation nonlinear boundary value problem differential inequality asymptotic expansion |
