Weighted Sobolev regularity and rate of approximation of the obstacle problem for the integral fractional Laplacian.
Resumen:
We obtain regularity results in weighted Sobolev spaces for the solution of the obstacle problem for the integral fractional Laplacian (−Δ)s in a Lipschitz bounded domain Ω⊂Rn satisfying the exterior ball condition. The weight is a power of the distance to the boundary ∂Ω of Ω that accounts for the singular boundary behavior of the solution for any 0
