Existence and uniqueness results for a coupled system of nonlinear fractional differential equations with two fractional orders.

In this work, we discuss the existence of solutions for a coupled system of nonlinear fractional differential equations involving two Riemann-Liouville fractional orders. By applying the Leray-Schauder's nonlinear alternative and Banach's fixed-point theorem the existence and uniqueness of solutions is obtained. [ABSTRACT FROM AUTHOR]
