The theory of u0-positive operators with respect to a cone in a Banach space is applied to the fractional linear differential equations
0 < t < 1, with each satisfying the boundary conditions u(0) = u(1) = 0. The existence of smallest positive eigenvalues is established, and a comparison theorem for smallest positive eigenvalues is obtained.
