| Abstract: | Using the singularly perturbed theory and the matching principle, the shock problems for a class of the nonlinear singularly perturbed equations are considered. Firstly, the outer and internal solutions of the original problem are constructed. Secondly, the shock solutions as the shock layer near the boundary and interior of the interval are studied. Finally, the expressions of the shock solution and shock location relation boundary conditions are obtained. |
