In this article, by the use of the lower and upper solutions method, we prove the existence of a positive solution for a Riemann–Liouville fractional boundary value problem. Furthermore, the uniqueness of the positive solution is given. To demonstrate the serviceability of the main results, some examples are presented.

AbstractIn this work we consider the unique positive solution for the following fractional boundary value problem $\left\{ \begin{gathered} D_{0 + }^\alpha u(t) = - f(t,u(t)),t \in [0,1], \hfill \\ u(0) = u'(0) = u'(1) = 0. \hfill \\ \end{gathered} \right. $ Here α ∈ (2, 3] is a real number, D 0+α is the standard Riemann-Liouville fractional derivative of order α. By using the method of upper and lower solutions and monotone iterative technique, we also obtain that there exists a sequence of iterations uniformly converges to the unique solution.

The upper and lower solutions method is used to study thep-Laplacian fractional boundary value problemD0+γ(ϕp(D0+αu(t)))=f(t,u(t)),0<t<1,u(0)=0,u(1)=au(ξ),D0+αu(0)=0, andD0+αu(1)=bD0+αu(η), where1<α,γ⩽2,0⩽a,b⩽1,0<ξ,η<1. Some new results on the existence of at least one positive solution are obtained. It is valuable to point out that the nonlinearityfcan be singular att=0,1oru=0.

In this paper, we consider a discrete fractional boundary value problem of the form -??y(t) = f(t+? - 1; y(t + ? - 1)), y(? - 2) = ?(y), y(? + b) = ?(y), where t ? [0,b]N0, f : [? ? 1,... , ? + b - 1]N?-2 x R ? [0,+?) is continuous, ?, ? : C([? - 2; ? + b]N?-2 ) ? R are given functionals, and 1 < ? ? 2. We show that provided that both ? and ? are linear functionals, then under certain conditions the fractional boundary value problem will have at least one positive solution even if neither ? nor ? is nonnegative for all y ? 0. This provides new results not only for the fractional boundary value problem but also in the case when ? = 2. Our results also generalize some recent work on the conjugate fractional boundary value problem. We conclude with two examples to illustrate our results.

Unique Positive Solution

In the present work, we discuss the existence of a unique positive solution of a boundary value problem for a nonlinear fractional order equation with singularity. Precisely, order of equation Dα 0+u(t) = f(t, u(t)) belongs to (3, 4] and f has a singularity at t = 0 and as a boundary conditions we use... Using a fixed point theorem, we prove the existence of unique positive solution of the considered problem.
