AbstractIn this paper, we consider a (continuous) fractional boundary value problem of the form −D0+νy(t)=f(t,y(t)), y(i)(0)=0, [D0+αy(t)]t=1=0, where 0≤i≤n−2, 1≤α≤n−2, ν>3 satisfying n−1<ν≤n, n∈N, is given, and D0+ν is the standard Riemann–Liouville fractional derivative of order ν. We derive the Green’s function for this problem and show that it satisfies certain properties. We then use cone theoretic techniques to deduce a general existence theorem for this problem. Certain of our results improve on recent work in the literature, and we remark on the consequences of this improvement
