چکیده
In this paper, we consider the properties of the Green’s function for the nonlinear fractional differential equation boundary value problem Dq0+u(t) = f (t,u(t)), t ∈ J := [0, 1], u(0) = u′(1) = 0, where 1 < q≤ 2 is a real number, and Dq0+ 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.
