We apply the quasilinearization method to a Dirichlet boundary value problem and to a right focal boundary value problem for a Riemann-Liouville fractional differential equation. First. we sue the method of upper and lower solutions to obtain the uniqueness of solutions of the Dirichlet boundary value problem.
