摘要: The purpose of this study is to acquire some conditions that reveal existence and stability for solutions to a class of difference equations with non-integer order μ∈ (1, 2]. The required conditions are obtained by applying the technique of contraction principle for uniqueness and Schauder's fixed point theorem for existence. Also, we establish some conditions under which the solution of the considered class of difference equations is generalized Ulam-Hyers-Rassias stable. Example for the illustration of results is given.

关键词: Fractional difference equation, Green's function, existence and uniqueness, Ulam-Hyers-Rassias stability, summation boundary condition
