%0 Journal Article %T Existence and Uniqueness of Positive and Nondecreasing Solutions for a Class of Singular Fractional Boundary Value Problems %A Caballero Mena J %A Harjani J %A Sadarangani K %J Boundary Value Problems %D 2009 %I Springer %X We establish the existence and uniqueness of a positive and nondecreasing solution to a singular boundary value problem of a class of nonlinear fractional differential equation. Our analysis relies on a fixed point theorem in partially ordered sets. %U http://www.boundaryvalueproblems.com/content/2009/421310
