Abstract. In this paper, the existence and uniqueness of solutions to a class of boundary value problems with coupled nonlinear Caputo fractional q-difference systems are considered. The existence of solutions is obtained by using Schaefer’s fixed-point theorem. The uniqueness of the solutions is achieved by using Banach contraction mapping principle, which supplements the existing literature. Two examples exhibit the feasibility of the theoretical results in applications.
