Abstract: We discuss the existence and uniqueness of solutions for the Langevin fractional differential equation and its inclusion counterpart involving the Hilfer fractional derivatives, supplemented with three‐point boundary conditions by means of standard tools of the fixed‐point theorems for single and multivalued functions. We make use of Banach’s fixed‐point theorem to obtain the uniqueness result, while the nonlinear alternative of the Leray‐Schauder type and Krasnoselskii’s fixed‐point theorem are applied to obtain the existence results for the single‐valued problem. Existence results for the convex and nonconvex valued cases of the inclusion problem are derived via the nonlinear alternative for Kakutani’s maps and Covitz and Nadler’s fixed‐point theorem respectively. Examples illustrating the obtained results are also constructed. (2010) Mathematics Subject Classifications.
