We study the existence of multiple solutions to the boundary value problem
where , is a parameter, , and are, respectively, the left and right Riemann-Liouville fractional integrals of order , is a given function. Our interest in the above system arises from studying the steady fractional advection dispersion equation. By applying variational methods, we obtain sufficient conditions under which the above equation has at least three solutions. Our results are new even for the special case when . Examples are provided to illustrate the applicability of our results.
