Our problem contains two Hahn difference operators and a Hahn integral. The existence and uniqueness of solutions is obtained by using the Banach fixed point theorem, and the existence of at least one solution is established by using the Leray-Schauder nonlinear alternative and Krasnoselskii�s fixed point theorem. Illustrative examples are also presented to show the applicability of our results. � 2017, The Author(s).All Open Access; Gold Open Accessboundary value problemsexistencefixed point theoremsHahn difference equationsuniquenessArticleScopus
