Abstract

Our research is about Sturm-Liouville equation which contains conformable fractional
derivatives of order α ∈ (0, 1] in lieu of the ordinary derivatives. First, we present the
eigenvalues, eigenfunctions and nodal points and the properties of nodal points are used for
the reconstruction of an integral equation. Then, the Bernstein technique was utilized to
solve the inverse problem and the approximation of solving this problem was calculated.
Finally, the numerical examples were introduced to explain the results. Moreover, the
analogy of this technique is shown in a numerical example with Chebyshev interpolation
technique .
