摘要：As we all know, both the past and the futurenonlocal memory effects can be characterized by the RieszCaputo derivative. A class of three-point boundary valueproblems for fractional differential equations with the RieszCaputo derivative is studied in this paper. We find the positivesolutions for the fractional problem by applying the technique ofmonotone iterative. Moreover, an iterative scheme for approximating the solutions is given in the paper. Finally, an exampleis given.
