The singular boundary value problem is studied in this paper.The singularity may appear at t = 0 and the function g may be superlinear at u = โ and change sign. The existence of solutions is obtained via an upper and lower solutions method.

โฆ Synopsis
This paper studies the existence and uniqueness of solutions of second-order three-point boundary value problems with lower and upper solutions in the reversed order, obtains the sufficient conditions for the existence and uniqueness of solutions by use of the monotone iterative method, and gives the iterative sequence for solving a solution and its error estimate formula under the condition of unique solution.

We study some four point boundary value problems. We use the method of upper and lower solutions to improve some previous existence results, and apply the generalized method of quasilinearization to obtain a monotone sequence of iterates converging uniformly and rapidly to a solution of the problem.
