Uniqueness and Existence of Positive Solutions for A Multi-Point Boundary Value Problem of Singular Fractional Differential Equations

Abstract

In this paper, we study the uniqueness of a positive solution for the singular nonlinear fractional differential equation boundary value problem , , , , where is a real number, is the standard Riemann-Liouville differentiation and , with . Our analysis relies on a fixed-point theorem in partially ordered set. As an application, an example is presented to illustrate the main result.
