The Iterative Technique for a Fourth-Order Three-Point Nonlinear BVP with Changing Sign Green’s Function

Abstract

In this paper we discuss the existence of a monotonic positive solution for the following fourth-order three points Non-linear BVP which has the sign - changing Green s function where and The point is that although the corresponding Green is changing the sign by applying iterative methods We can still obtain the existence of a monotonic positive solution under certain suitable conditions of f
