- Abstract
The existence and asymptotic estimates of solutions for a class of singularly perturbed boundary value with the internal layer problem is investigated. Assume that the solution of the degenerate equation is not smooth at the defined interval. By using the boundary function method and the sewing method, the formal asymptotic solution is constructed. Then the existence of the solution are proved by using the theorem of lower-upper solutions, and an exact solution is estimated. Finally, an numerical example is presented as an illustration.
