Exponential convergence of hp-FEM for the integral fractional Laplacian in 1D
(2022)SAM Research ReportWe prove weighted analytic regularity for the solution of the integral frac tional 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.Report -
