Abstract

In this paper, by using the endpoint result for multifunctions, we investigate the existence of solutions for a boundary value problem for fractional differential inclusions with sum and integral boundary conditions. Finally, an example is also given to illustrate the validity of our main result.

Introduction and preliminaries

The topic of fractional differential equations is one of the branches of mathematics which has various important applications in many fields as mathematics, physics, chemistry, biology and many other branches of engineering. Many papers have published about fractional differential equations by researchers which apply the fixed point theory in their existence theorems. For instence, one can find a lot of papers in this field (see [1], [2], [3], [4], [5], [10], [11], [12], [13], [14], [15], [17],

Main result

Now, we are ready to prove our main result. Let X={u:u,u,cD0piuC(J,R)} endowed with the norm u=suptJ|u(t)|+suptJ|u(t)|+i=1ksuptJ|cD0piu(t)|. Then, (X, ‖ · ‖) is a Banach space [32].

Lemma 2.1

Given yX, then the unique solution of the problem {cD0αu(t)=y(t),0<t<1,2<α3,u(0)+j=1mbju(0)=0,γ1u(η)+γ201u(τ)dτ=0,j=1mbju(1)+γ301u(τ)dτ=0,is given by u(t)=0t(ts)α1Γ(α)y(s)ds+γ1ΔA(t)0η(ηs)α1Γ(α)y(s)ds+1Δ(γ2A(t)+γ3B(t))010τ(τω)α1Γ(α)y(ω)dωdτ+1ΔB(t)j=1mbj01(1s)α2Γ(α1)y(s)ds,where A(t)=
