【Abstract】 In this paper, third order Singularly perturbed boundary value problem is studied by means of differential inequality theories. Based on the upper and lower solution, the uniqueness theorem is established. Specific upper and lower solutions are constructed, and the uniqueness of solution is obtained. The result shows that it is a new approach to apply these techniques to solving the uniqueness of singularly perturbed boundary problem.更多还原
