| Abstract: | A class of two-parameter and nonlinear boundary value problems with singular perturbation for higher order differential equations are studied. The formal asymptotic solutions are constructed by the composite expansion method. By using the theory of differential inequalities, the existence of solutions for the original problems and the uniform validity of the formal asymptotic solutions are proved. |
