Coupled Systems of Fractional Integro-Di erential Equations Involving Several Functions

Abstract

This paper studies the existence of solutions for a coupled system of nonlinear fractional integro-dierential
equations involving Riemann-Liouville integrals with several continuous functions. New existence and uniqueness
results are established using Banach fixed point theorem, and other existence results are obtained using Schaefer fixed
point theorem. Some illustrative examples are also presented.
