abstract = {<p style="text-align: justify;">In this paper spectral Galerkin approximation of optimal control problem
governed by fractional elliptic equation is investigated. To deal with the nonlocality
of fractional Laplacian operator the Caffarelli-Silvestre extension is utilized. The first
order optimality condition of the extended optimal control problem is derived. A spectral Galerkin discrete scheme for the extended problem based on weighted Laguerre
polynomials is developed. A priori error estimates for the spectral Galerkin discrete
scheme is proved. Numerical experiments are presented to show the effectiveness of
our methods and to verify the theoretical findings.</p>},
