%0 Journal Article %T Existence of positive solutions for singular fractional differential equations %A Tingting Qiu %A Zhanbing Bai %J Electronic Journal of Differential Equations %D 2008 %I Texas State University %X In this article, we establish the existence of a positive solution to a singular boundary-value problem of nonlinear fractional differential equation. Our analysis rely on nonlinear alternative of Leray-Schauder type and Krasnoselskii's fixed point theorem in a cone. %K Boundary value problem %K positive solution %K singular fractional differential equation %K fixed-point theorem %U http://ejde.math.txstate.edu/Volumes/2008/146/abstr.html
