摘要：
In this paper, we consider the properties of the Green’s function for the nonlinear fractional differential equation boundary value problem D0+qu(t)=f(t,u(t)), t∈J:=[0,1], u(0)=u′(1)=0, where 1<q≤2 is a real number, and D0+q is the standard Riemann-Liouville differentiation. As an application of the Green’s function, we give some multiple positive solutions for singular boundary value problems, and we also give the uniqueness of solution for a singular problem by means of the Leray-Schauder nonlinear alternative, a fixed-point theorem on cones, and a mixed monotone method.
