We study the regularity of minimizers of the functional E(u) := [u]2Hs(Ω)+ ∫ Ω fu. This corresponds to understanding solutions for the regional fractional Laplacian in Ω ⊂ R . More precisely, we are interested on the global (up to the boundary) regularity of solutions, both in the case of free minimizers in H(Ω) (i.e., Neumann problem), or in the case of Dirichlet condition u ∈ H 0(Ω) when s > 1 2 . Our main result establishes the sharp regularity of solutions in both cases: u ∈ C(Ω) in the…

We obtain the integration by parts formula for the regional fractional Laplacian which are generators of symmetric α-stable processes on a subset of $$\mathbb{R}^{n}$$ (0 <  α  < 2). In this formula,
