This paper investigates the boundary value problem of a class of fractional (p, q)-difference equations involving the Riemann-Liouville fractional derivative. A sufficient condition for existence and uniqueness of solutions is obtained using the generalization of Banach contraction principle, while a sufficient condition for the existence of at least one positive solution is established by applying a fixed point theorem in cones. Several examples are presented to illustrate the main results.
In this paper, we investigate the boundary value problem of a class of fractional (p, q)-difference equations involving the Riemann-Liouville fractional derivative. Based on the generalization of Banach contraction principle, we obtain a sufficient condition for existence and uniqueness of solutions of the problem. By applying a fixed point theorem in cones, we establish a sufficient condition for the existence of at least one positive solution of the problem. As an application, some examples are presented to illustrate the main results.
