In this study, the Banach contraction principle and Schaefer’s fixed point theorem are employed to establish, respectively, the uniqueness and existence of solutions for a coupled fractional differential system subject to mixed boundary conditions. These conditions consist of Dirichlet conditions and nonlocal fractiona...
