Query: Exponential convergence of hp-FEM for the integral fractional Laplacian
  in 1D   We prove weighted analytic regularity for the solution of the integral
fractional Poisson problem on bounded intervals with analytic right-hand side.
Based on this regularity result, we prove exponential convergence of the hp-FEM
on geometric boundary-refined meshes.
