Upper and lower solutions method and a fractional differential equation boundary value problem. Abstract. The method of lower and upper solutions for fractional differential equation D δ u(t)+ g(t, u(t)) = 0, t ∈ (0, 1), 1 < δ ≤ 2, with Dirichlet boundary condition u(0) = a, u(1) = b is used to give sufficient conditions for the existence of at least one(More)
