Existence and Uniqueness of a Positive Solution for Four-Point Boundary Value Problems in a Cone.

Abstract

In this thesis, we constructed the Green's functionfor corresponding homogeneous equation by using its properties. Under the suitable conditions, we established the existence and uniqueness of positive solution for four-point boundary value problems by applying Krasnoselskii's fixed point theorem and Banach contraction principle respectively. This study was mostly dependent on secondary source of data such as journals, books which related to our study area and internet
