One method for the boundary value problem eigenvalues calcuating for a second-order differential equation with a fractional derivative.

In this paper, we give a formula for computing the eigenvalues of the Dirichlet problem for a differential equation of second-order with fractional derivatives in the lower terms. We obtained this formula using the perturbation theory for linear operators. Using this formula we can write out the system of eigenvalues for the problem under consideration. [ABSTRACT FROM AUTHOR]
